EXCLUSIVE PREMIERE: Doom Shrugs - "The Clairolfactant and the Flatulent Ghost"

Weird is the operative word to describe New Zealand's Doom Shrugs. This is weird and wonderful stuff. This is math rock with a fast and loose feel, so to speak, with off-kilter, nauseating rhythms and a number of improvised sections. Clean guitar tones and tight percussion drive this album, but there are sparse sections of shouted vocals as well. "The Clairolfactant and the Flatulent Ghost" is thought provoking in how it flaunts the normal conventions of music, recalling the math rock zaniness of bands like Hella and the jazz injected improvisational madness of John Zorn and his associated projects. This editor had an almost an identical experience to the first time I heard Horse Torso, especially given that this is obviously supposed to be music that makes you feel uncomfortable. It's very fidgety. Funnily enough, this album's vibe could be described by one of the song titles: "I Feel Overwhelming Joy, Please End My Miserable Life."

Doom Shrugs - "The Clairolfactant and the Flatulent Ghost," out 9/7/18.

EXCLUSIVE PREMIERE: The Sound That Ends Creation - "Roses and Thorns and Dead Unicorns"

Chris Dearing, the mastermind behind Texas mathcore / grind project, The Sound That Ends Creation, has come a long way. After releasing "Fitting Through the Crawlspace Between Rhyme and Reason" less than a year ago and appearing on Mathcore Index: Volume 4, TSTEC is back with his 3rd full-length, and it sees some of best work from the solo artist yet. With artwork done by Connie Sgarbossa of SeeYouSpaceCowboy, one can almost assume what kind of music one is going to encounter here, but the album also briefly broaches some electronic elements and includes a small saxophone feature. "Roses and Thorns and Dead Unicorns" is immediately reminiscent of the glory days of MySpace, and with it's cut-out art aesthetics, harsh vocals, art-grind freak outs, and abundant audio samples (Trailer Park Boys fans, rejoice), all that's missing is that white belt hanging in your closet.

"Roses and Thorns and Dead Unicorns" drops June 30th 2018 on Bandcamp.

Interview with Standards

Mathcore Index correspondent Levi Sebastian* interviews Los Angeles instrumental math rock duo, Standards.

Originally aired on Mathcast Episode 22: 6/28/18.

*additional commentary by Christian Segerstrom

Read the transcription here:

Mathcore Index: How'd you guys meet?

Marcos: Well, I had a change of course in my colleging, and I decided I want to study music, so I got into CalArts (California Institute of the Arts) and I was really blessed to get in as a guitar performance major, and my very very first class ever I see this guy walking in with like a green shirt and then a slightly greener hat and like "oh that guy looks cool," and then I was in a touring workshop and it was like a three-day crash course like a little mini thing before these classes started and it was like how to tour and stuff and so this guy was the only guy in the class then. He was the only person and I was like, I've got to talk to this guy. He's really cool. I was still trying to figure out what I wanted to do with everything. I'd actually studied with Nick Reinhart from Tera Melos, so I'd taken lessons with him. I had a little bit of like expertise in that and then I was listening to a lot of cool bands, but I was actually like really into indie rock and stuff. So I didn't really know what I wanted to do, but I wanted to feel it out and just play with different musicians. 

Mathcore Index: (to Jacob) What was your background before meeting him?

Jacob: I studied math and music at UC Berkeley before and I was kind of doing a lot of research there and working on computer programming stuff and then one summer when I was working at this place called JPL, in Pasadena, actually where I live now, I was playing in a band with my friends, and actually it's funny because it was this math rock band that I was in high school, and I hadn't really played any of that kind of music since then like I've been more into jazz for a long time and just other other kinds of music: hip hop, R&B, and all that kind of stuff super technical music already. So yeah, just all kinds of different stuff, and at that time I realized like, what what music really meant to me and how it was and so I decided to go full speed ahead for that thing, and then I ended up going to CalArts for grad school, and in the Jazz Studies Program and I kind of like got everything together at that point. Was working on my own music, composing, playing drums learning piano, all this different stuff, and I guess at the time that we had met my main project was (still one of my main projects) called Battery, which is a solo drum set and electronics project, and so that was the project that I had toured with and it's this kind of like jazz centric project where I'm triggering synths with my drum triggers and there's a lot of improvisation in it and all this kind of stuff. 

Macros: Shit, you guys should cover it.

Mathcore Index (Levi): Did you know about this Christian? 

Mathcore Index (Christian): I did not know about battery.

Jacob: Yeah, well we did we actually did in on this tour we've actually done a couple of Battery / Standards shows. So in Arcata, we did a workshop. That's another thing. So we're both from we both met in Humboldt, basically.

Levi: Oh, yeah, us both I sold him weed at a dispensary and we both saw each other's t-shirts basically. 2007 to about 2008 and so we we booked shows in a house in Manila forever. There's so many fucking houses shows in Arcata. It's all houses: The Bat Cave, which is... 

Jacob: Oh yeah, I know The Bat Cave.

Mathcore Index: Oh, okay. Cool. 

Marcos: Actually did some workshops there and Jacob went into like this deep, deep like, explanation of all this shit and then I just was like, here's how you play like, you know the Cantina song

Mathcore Index: Are you gonna do another show with Battery?

Jacob: It's kind of like wherever it feels right because the thing is when I play Battery right before Standards I'm basically dead at the end. So usually when I'm playing with Standards it's definitely like taxing, but when I do both of them, it's like the craziest shit. In Arcata I was down and I think we're playing at those cafes in San Luis Obispo in like two days, so maybe I'll do it there but probably we'll probably just play it as standards.

Mathcore Index: Would you guys rather do a house show or a stage show on any given day?

Marcos: I mean, it depends on the mood. I definitely think there's perks to both but after having played a ton of house shows it feels really refreshing to play at a real venue and get treated like, I don't know, less like friends and more like musicians. The relationship here is very curt. Just also having everything mic'd up and controlled by someone who's obviously really good. That's why we wanted to play here. It sounds awesome. So a house show it's like oh like, yyou know, something is not loud enough. That's that's just the deal, but also there's that raw DIY energy that I think we've both come out of really strong that we really feel in touch with the house shows. We did a couple venue shows and after we played we did a string of house shows and we felt really refreshed. So I think a healthy balance is really good.

Mathcore Index: With the you guys being a two piece playing house shows, obviously nice you guys fit in the house and everything. What did the perks and also just the cons I guess of just being a two piece?

Marcos: Well for me, I'm covering a lot of melodic ground, so what I do is I have a guitar and I split it into two signals: one of the signals goes just throw all my pedals and then the other one goes into an octave signal which has a range feature on it, so it only activates when I play the lowest three strings on my guitar and that goes into a bass amp. So we get a cool stereo effect. And also we have like a low end so I'm playing guitar and bass. Obviously the upside is we're touring in my Prius. Spent like nothing because it's just like really easy to zip around and everything is really easy just to do as a band, like go out and do practice. I just text Jake and I'm like, "hey, dude wanna practice?" He's like "cool." It's not like a group chat. Someone's at work...we have to like put schedules together. It's just like "hey, man. Are you free Tuesday night? Dope.

Mathcore Index (Christian): Yeah, being the only tonal instrument and touring van is obviously very challenging, but you have that, you know, the two-handed technique which gives you the opportunity to cover more a lot of ground as you say.

Marcos: ...but even then sometimes I wish I had a third arm to add something extra, so we might just experiment with either looping or...we just don't know, I guess we're just gonna see because we're working on our next release already and we're just trying to see if we can come up with more thought-out compositions because it's usually just like: riff, polyphonic part, then another riff, and then maybe like little drum fill. So we're really kind of limited to what we can do, but we're trying to expand that.

Jacob: I think I feel like we're less limited than we think. I think that there have been so many times in this journey that we've taken so far where it's been like, "Oh, man, we can't get the bass sound" or like, you know when we were mixing the record like shit, man it's never gonna sound bass enough. We need to get a bass player, but I think that this whole thing is just like an exercise in limitation, and that's the same thing that I've really experienced in my solo project where it's like I have this drum set. I have this programming language that I'm using and it's actually quite limited. How do I create a full song as a performance? It's actually very freeing to have this set up because there's you know, interesting challenges that happen . So you're solving those challenges by playing all these polyphonic parts and then for me, it's like my goal is to be able to highlight all of those at once. So for example, he might be playing a polyphonic part where there's a polyrhythm between the hands, and I myself am playing that polyrhythm between limbs. So it's like we're kind of doing the same thing, we're both just drumming on our instruments really.

Mathcore Index: So really, I'm getting there's a lot of pros here you guys are working with being a two-piece but really no downside of being a two-piece, you just don't have a bassist.

Marcos: I mean there there was a huge one in that when I started I couldn't play independently with my hands and I actually had to train for several months to do it. I started with Britney Spears' "Whoops I Did It Again." So basically I started the chord and then changing the chords as I'm playing the chords and that took me like a week just to do that and then I was like, okay great. And then I learned Fur Elise which is like the basic basic piano song. So then I got that that took like a month and then just can I do scales with this hand. Can I do some scales with two hands? So I like really methodically built it up,  and then now I'm trying to learn Mozart and Bach, so I put a lot of time into making sure we could do it and I'm really pleased with the results.

Mathcore Index: We are too. So with the videos Facebook: there's a lot of them. You guys are playing outside, inside, posting the shows and everything. Other than just posting to show everybody what you're doing, is there any other reason why you do it.

Jacob: Yeah, so as a musician or specifically as a band in 2018, it's like, what is your output? And then that's the question I was like, what is your work? Is your work just your albums? Is your work just your shows? Are those things connected and for us? Everything is connected. Literally every single story. Everything we post on Instagram, every single thing we put on Facebook, it's all part of part of the world that we occupy in our own lives, you know what I mean? Literally everything that we do is sharing the things that we care about. Sharing our vibe. It's not like "I hope I can post this thing." I mean, obviously there's a little bit of that where it's like, "oh, I want to post this thing because I know people will like it" or whatever, you know, but it's also like as an artist and I've seen so many other people do this actually...and one really funny example, is this kind of meme pop artist named Oliver Tree. Everything that you put online is like a piece. It's like a piece of work. You know what I mean? And so like if you're treating every single thing that you put out with care and you really feel like it represents what you do in all these different ways like, you know, we're musicians, we're making music but we also produce photos. I take a photo myself and put it on on the Standards page, that's part of Standards.

Marcos: It's really an extension of our art form and I think a lot of bands are just like, okay "we're playing a show tonight. Thpppt." I'm not hating on that because obviously we're just looking at it differently, but we see that as an extension of our art form and I think those videos are really creative. We get really really creative with them and they're a lot of fun to me. On this entire tour, we've probably played to from four people to 90 people per show. So we've played like 13 days already, 12 days or whatever. So I'm not very good at math, but that's not as many as even one of our videos that we'll put up at any given time, because one of our videos has anywhere from like a thousand to ten thousand views, so that's instantly more than we'll ever play to in a given year maybe. It's crazy to think that if you're taking advantage and and treating that as an art form as I get an extension of your performance, you know, and people like artists that that really capitalized on what was coming out, you know, Michael Jackson with music videos. 

Mathcore Index: You definitely have a strong visual aesthetic - 

Marcos: And I think Internet is the new thing and I think and like if you want to be out there doing it, especially just like Oliver Tree, an amazing example, you have to have that you have to think about it like that.

Jacob: You can think about it like that and we we choose to think about it like that, but I think that there are also so many bands. We were just talking earlier today with our friends who are in this really great post-punk band called Patti, and we were talking about this other band called Black MIDI...

Marcos: ...they're one of my favorite bands and I've never been to a show and they have no music out, but there still there one of my favorite bands. They made a Facebook and then they just announce the shows that day, so I think that that's just like part of their art form. Your online presence is your art form, whether you have one or you don't, and these are all like artistic choices that we make as musicians. We just happen to choose this because, I mean at least on my end, I really enjoy documentation. I really enjoy curating the shit and just having like oh yeah, we're playing the song, but it really feels like it needs like a yellow background. So we're gonna put a yellow background on it. 

Mathcore Index: So the next thing: the aesthetics here. What is going on with the first release with the grass and now you got the Kiwis and fucking avocados, kale, all that kind of stuff. What's going on?

Marcos: We've kind of I've kind of always done this when it was just me and he's kind of always done this too, and now we just do it together, but we really are into fruit and we just feel it represents our music. 

Jacob: Well, for me, well...I love food so much. I'm wearing cherry hearings right now. I hope they don't like gauges to you, they're little circles, but yeah, they're just just cherries not gauges. But yeah, I have these other ones that are like a fork and a spoon, and that just like kind of represents my relationship to food. I've always been super into cooking huge amounts of food, storing it for like nine days and just having all this stuff, all these vegetables and stuff, and I just really enjoy veggies and fruits and making smoothies and all this stuff. So the love of this, you know, the natural world but specifically that in natural foods and you know, that kind of contributes to that whole thing. 

Mathcore Index: Will you ever have vocals? Why don't you have vocals?

Jacob: When you have vocals, there's a very clear communication of concepts, right? Like you say "I'm sad because I had a bad day," you know?

Marcos: That there be a vocal line: "I'm sad because of the world," and that's what you're saying. But you can also express this with instruments. It's just not as clear because music is a language, but English is also a language. Like, maybe you listen to a song in French and you aren't understanding the words, so it's almost similar. So yeah, to me, because I don't know any French it's similar to me to instrumental music because the voice is just another instrument. So if you understand that language, it's very easy, like very ground floor. Like, I'm sad because the world is get what I'm saying already and the music will match that and the music works around that. What we're doing is like a dialogue. It's like a conversation and we're both speaking through our instruments and we get to do things that we cannot do in other ensembles because we're basically chatting it up and it's the musical language. So some people that don't listen to a lot of instrumental music or haven't thought of that concept, it is a little jarring to them or something, but if you listen, there's stuff there. 

Jacob: Instrumental music foregrounds the personalities of the players and the styles and character of those different players. That totally happens in a non-instrumental setting, like there's obviously personalities of the individual players. We feel like with instrumental music you're really able to show who you are super openly and then the concepts that are communicated can be a little bit more, I don't want to say universal, but there's just more ways to enter into what the music means to you, and that's something that I really enjoy. I mean, I love vocal music as well, but you know...

Marcos: It transcends language, it transcends culture. It's really, you know, people can really dig it no matter what because it is one of those things. It's the language of people, music.

Mathcore Index: So I'm gonna say you guys are going to stay instrumental, correct? 

Jacob: We're kind of just biting off little chunks. I think definitely for a while.

Mathcore Index: I saw your influences on Facebook, CHON, a lot of jazz artists and everything. They're really good instrumental  band and they threw the vocals in then they got rid of them again. So yeah, that's why I asked.

Jacob: I mean, I'm down for a vocal feature like Axl Rose. Hit me up.

Mathcore Index: We know him. Don't worry about it. 

Standards: Cool. Perfect.

EXCLUSIVE PREMIERE: Snakehound - "Imitation Crown"

You may remember Kansas City's Snakehound from the video premiere we did earlier this month, and today we have the pleasure of bringing you an early stream of their new album, "Imitation Crown." Snakehound are a brand new band, but have already made waves in the online community with series of singles showcasing high-energy metalcore with earwig riffs and pull-offs aplenty. The album begins with the moshy "Dignified Rats," and as the band doesn't skip on the vicious hardcore riffs and breakdowns, it only gets better from there." "Gypsy Danger" playfully dials it back only momentarily before launching into "Guillotine del Toro," which aside from "Timberline" may very well be the best representation of the band's sound; Snakehound bring the energy of Converge with the technicality of Botch, and combine it with the groove and heaviness of their disciples in Every Time I Die, Norma Jean and The Chariot, and "Guillotine del Toro" is a delightful exhibition of these influences. "Snakes for Legs" is as off-kilter as the name suggests, and brings some sickly, chromatically descending diminished chords a la Daughters, but doesn't linger there for long, as it soon gives way to feedback and harmonics, which fades perfectly into “Timberline," the video of which being the aforementioned premiere. The record then has it's only moment of respite with the brief interlude, “28:06:42:12," before jumping back into the action with the albums first single "Autumn Driver," our first taste of what Snakehound had to offer. The next track, "Northern Viper," is seemingly ironically titled as it most features mostly southern rock riffs, but the band soon resumes a more serious assault with “Hornets for Hands" and "Bitter Tempest," which boast a few of the more technically impressive sequences on the album. The album's finisher, "Five Eyes," finally brings it to it's conclusion with a lurching, feedback riddled anthem.

Pre-order "Imitation Crown" now on Bandcamp.

EXCLUSIVE PREMIERE: goner. - “goner.”

In recent years the metal and hardcore scenes, including their respective aesthetics, have become hopelessly intermingled. Along with their similar social, political, and anti-religious themes, the sounds of blast beats and breakdowns, circle pits and 2 steps, growling and shouting, now all exist happily under one larger umbrella, despite some waging a tireless war of classification, e.g., "that's not metal," or my personal favorite, "that's not grindcore," an expression I often hear pertaining to Myspace era bands. Goner are one such example of this current amalgamation that spring to mind. Hailing from Syracuse, New York, also home of legendary Ed Gein, it's no surprise that the three piece is somewhat genre defying, and given the rise of bands like Nails, End, Helpless, and other HM2 driven metallic hardcore and grind, Goner have picked a perfect time to carve out their niche in an ever evolving scene. "My Experience Has Molded Me Into the Failure You See Before You" begins the EP with fast and vicious riffing, and with the exception of one HUGE whammy breakdown in "The Great Deceiver" (the mixing by Outlier SoundPedram Valiani of Frontierer and Sectioned should be extremely evident here), the self-titled EP scarcely relents until the conclusion of "Caretaker."

Preorder the debut EP from goner. here.

EXCLUSIVE PREMIERE: Sense Offender - "I"

There has a been a huge wave of technical and filthy hardcore bands emerging from the UK in the past few years: Frontierer, Sectioned, Helpless, Leeched, Dark Habits, Bed of Wasps, and Gendo Ikari to name a few, and Sense Offender are certainly no exception either. Given the band features a member of another similar, more established act, GeistSense Offender already have a correspondingly established hardcore pedigree and know exactly which buttons to push. However, where Geist and Sense Offender diverge is the more acute sense of hopelessness and despair of the latter. Sense Offender have trimmed the fat in favor of more dissonant passages that are alternatingly more driving and heavy, pulsating and mesmerizing, in a way that recalls the misanthropic stylings of Cult Leader or their former manifestation, Gaza. The EP's first track is a sample laced feedback loop that is the setup for the EP's true opener, "Prophet-Less," which launches an assault of odd-timed chording before a turn-on-a-dime change into it's big d-beat riff, quickly back into dissonance (where this release most happily dwells), and finally wrapping up with a hypnotic, slower riff, illustrating the band does know how to occasionally let off the gas and exercise dynamics."Starving Pigs," the EP's single, boasts an off-kilter, pulling middle section which draws with the force of a black hole. "Anointed with Seizures" begins with punishing riffs that are a trademark of this release, before giving way to a clean interlude, though band does not tarry here long, as the song quickly launches back into it usually attack before the eventual throbbing fadeout of "Weigh My Pieces." If this EP is any indication of the musical direction this band is headed, Sense Offender are a band to watch.

Arms / Seizures split 7"

At long last, stream the new Arms / Seizures split now via Metal Injection, featuring a guest appearance from Chad Kapper of Frontierer.

"The Orlando Math maniacs of Arms are back this month. The Floridians made a splash with their 2016 effort, BLACKOUT, and look to bridge the gap between major releases with a new split with Seizures. Their two new tracks, "Junk Witch" and "Pentigroid Alcheum," showcase a remarkable progression in the band's sound since we last heard from them. The quartet has greatly expounded their sonic range. Take a look at "Junk Witch" which opens on a progressive, partially jazzy section before unfurling into Arms' typical frenzy.  "Junk Witch" capitalizes on the contained cacophony the band has made since their inception as well. Yet, in songs like "Pentigroid Alcheum," the quartet calls to some of their inspirational roots. The track features a guest spot from Frontierer vocalist, Chad Kapper. With his help and Arms' penchant for the unhinged, this song is certainly the more ferocious of the two. It taps into early Botch and Dillinger Escape Plan much more than anything prior it seems. Still, this track when juxtaposed with "Junk Witch" or much of BLACKOUT proves Arms' metallic artillery continues to grow. It bodes well for the young quartet's future.

With The Dillinger Escape Plan stepping aside, an entity like Arms certainly seems fit to fill that void."

Interview with xdadcorex podcast

Recently had the pleasure of doing an interview with the homies over at xdadcorex podcast about mathcore and some other unspeakably nerdy shit you should probably just hear for yourself.

EXCLUSIVE PREMIERE: Aberrant Phase - "End Is Near"

While recently perusing the mathcore tag on Bandcamp, I discovered a great band from my very own city of which I had not yet heard. Given the dearth of such music in the Bay Area, I was astonished to discover a band of like-minded musicians who weren't playing black metal or crust. Aberrant Phase are that band, and after quickly getting in touch with the members, today we have the pleasure of bringing you an exclusive stream of their new EP, "End is Near." The semi-eponymous first track is not unlike The Dillinger Escape Plan's ballad "One of Us Is the Killer," the tremulant vocals guiding the soft instrumentation into the final breakdown's crescendo. The EP then kicks into a higher gear with "Dementia" and "Ghost Farm," finally slowing to a lurch for the finale of "Storms," all of which are reminiscent of "Jane Doe" era Converge, and throughout this record (and moreover their whole discography) there is an air of the 90's and early 2000's that very much recalls other seminal bands such as Botch and Cave In, the proto-mathcore / "math rock before the twinkles" band, Dazzling Killmen, or even their contemporaries in Seizures or Fero Lux.

tl;dr: if you remember the word "noisecore," this will probably be your new jam.

Aberrant Phase are to release their new EP, "End is Near," February 27th.

Best of 2017

Mathcore Index's Best of 2017


After various delays, complications, and delinquent submissions, we decided to finally bring you our 2017 year end lists in article form, despite the fact it's absurdly late. Better late than never though, right?


10) Worry - "A Celebration of Suffering"

Ex-The Great Redneck Hope members illustrating just how much Colorado knows heavy.

9) Artificial Brain - "Infrared Horizons"

Brooklyn's best angular death metallars give the plethora of other Gorguts acolytes a run for their money.

8) Czar - "Life Is Way No Way to Treat an Animal"

Czar are keeping the lost art of jazzcore alive.

7) Puncture - "Form and Void"

Those of you complaining about Cult Leader's stylistic change after Gaza should immediately investigate this highly aggressive album.

6) Cleric - "Retrocausal"

An absolutely expansive masterpiece that took a long time to truly digest, given the sheer magnitude and ambition of the song writing.

5) Yowie - "Synchromysticism"

Speaking of expansion, Yowie's latest mind-expanding release is their magnum opus, and is as challenging as it is infectious.

4) Mico - "Segunda Muerte"

Columbia brings one of the most inspired yet conversely under-recognized hardcore albums this year, with a seamless darkened tinge that could be compared to Plebeian Grandstand.

3) Helpless - "Debt"

One of Holy Roar's best signings ever, Helpless appear on Mathcore Index: Volume 1, and show with this effort that they can deliver a masterful full-length performance that is filled with earwig riffs and Gaza-laced evil passages.

2) Converge - "The Dusk In Us"

Big surprise, right? Not even being lazy here, just genuinely jammed this a ton, according to both and Spotify.

1) The Heads Are Zeros - "The Heads Are Zeros"

The Heads Are Zeros' self-titled full-length is both their magnum opus and their swan song, and bands like this are the reason I started "writing" about music.


10) The Callous Daoboys - "Animal Tetris"
9) Ladybird - "I Feel Nothing / I Exist Nowhere"
8) Mouthbreather - "Pig"
7) End - "From Unforgiving Arms of God"
4) SOUNDING - "Trepanation"
3) Good Game - "Don't Blow It"
2) Snooze - "Actually, Extremely"
1) SeeYouSpaceCowboy - "Fashion Statements of the Socially Aware"


So Christian did EPs and full-lengths, but I'm just gonna do a mixed top 10.

10) Dying Fetus - "Wrong One to Fuck With"

Wanted this higher on my list, but it was nowhere near as good as other albums like "Reign Supreme."

9) End - "From the Unforgiving Arms of God"

Just angry and good.

8) Kublai Khan - "Nomad"

Solid heavy hardcore.

7) Converge - "The Dusk In Us"

Thought I would've jammed this more, but didn't quite as much as I expected.

6) Snooze - "Actually, Extremely"

Go-to feel good music

5) Good Game - "Don't Blow It"

A no-brainer.

4) King Krule - "The Ooz"

My genre switch up.

3) The Heads Are Zeros - "The Heads Are Zeros"

A ride off into the sunset.

2) Less Art - "Strangled Light"

Members of Curl Up and Die, 'nough said.

1) Primitive Man - "Caustic"

"It's doom, dude."
