Site migration

The time has come to finally migrate to a slightly less antiquated platform. Blogger has served us well for the past 3 odd years*, but in the coming weeks posts will stop appearing here as we redirect traffic to our new website.

*EDIT: 10 years if you count the OLD website.

For the first time in about 18 months, we have shirts again. The first 50 sold out quietly in 3 days, so we went ahead and printed another 50 of our original logo design on black Gildan cotton t-shits. 

Order here.

Delta Sleep: Interview + Photo Essay

Delta Sleep are one of the most profoundly moving bands I have discovered in recent years, quickly becoming one of my favorite acts in math rock and at large, and back in November we had the honor of meeting them for a chat ahead of their performance at Bottom of the Hill in San Francisco.

Mathcast: Photo Essay

We've been doing our companion podcast, Mathcast, for a little over 2 years now. It is both a labor of love and joyful monthly ritual in which we discuss some of brightest artists in extreme and underground music, and last September our good friend and photographer, Vincent Courtoy, sat in on a recording session to capture that joy.

Mathcore Index 10th Anniversary

Just wanted to share with you that Mathcore Index is now 10 years old. We want to thank you all so much for your support, especially those of you who’ve been here since the beginning, as we continue to grow and expand our content. Mathcore Index was quite accidentally started by Simon Richard in 2009 as he was in the process of creating a MySpace profile for a new band: after accidentally creating a standard profile as opposed to an “artist” one, he decided to leave it up as way of sharing music and to help document the growing scene. Since then, we’ve been doing our best to bring you compilations, exclusive premieres, interviews, and more recently our podcast and Mathcore Index Fest, which will hopefully become an annual event. Thank you so much for supporting underground music. We love you all. -Mathcore Index (Christian, Simon, Carson, Levi, Sidd, Jay, and Kate) /// original logo and banner by Keith Carlson, art by Karl Frandsen.

EXCLUSIVE PREMIERE: Needle Play - "Doomster Baby"

Needle Play are a mathcore band based out of Boston, Massachusetts. Formed in late 2017, the band was originally featured on episode 23 of our podcast before seeing a slight lineup change with the addition of pianist Jonathan Jasperse and vocalist Tyler Tremblay, bassist and backing vocalist of MouthBreather, who both add exciting new energy to this already promising project. Tremblay's time in MouthBreather has obviously paid off, and it's clear by this raw vocal performance that he is equally comfortable with the role of front-man. Needle Play also further play to their already jazzcore leaning tenancies with the addition of piano accompaniment, and today we have the pleasure of bringing you the first single from their debut album, "Cruel Spring," which certainly highlights that. Fans of mathcore stalwarts, The Number Twelve Looks You, and next-gen mathcore darlings, like NoiSays, which also feature abundant jazzy interludes and off the wall time changes, will be all over this.

"Cruel Spring" is out April 9th via Bandcamp

EXCLUSIVE PREMIERE: Steaksauce Mustache - "Dance Cops"

If you couldn't tell by the name, Steaksauce Mustache don't take shit too seriously. The band have been bringing their special brand of humor to the PNW for the past 5 odd years, quickly growing a reputation for zany live shows with off-the-wall antics:

Now Steaksauce have returned with what is more or less their 3rd full-length effort via Silent Pendulum Records (The Number Twelve Looks Like You, Dead Empires, et al), and they are not fucking around. I mean, they are but er...well, you know what I mean. The band channels all the best elements of hardcore / mathcore acts like Every Time I Die, The Chariot, and The Dillinger Escape Plan, all with their signature hilarious gusto, and today we have the pleasure of you bringing the first single from their new album, "Superwoke." "Dance Cops" lives up to its name, starting off with an infectious 2-step and quickly moving into the chaotic space the band most often occupies. Also, there's abundant use of the whammy pedal, and who doesn't love that?

"Superwoke" is out March 15th via Silent Pendulum Records.

EXCLUSIVE PREMIERE: Freighter - “Psychic Reading ‘94”

My heart jumps a little each time I discover a new chaotic, technical, or progressive act coming out of California, especially when it's coming out of the Bay Area. Although Freighter were originally conceived in Wisconsin in 2006, the band has since relocated to San Francisco, and today we have the pleasure of bringing you their first single in 11 years, "Psychic Reading '94." The band plays a blend of progressive metal and mathcore akin to SikTh, The Dillinger Escape PlanProtest the Hero, and Cleric, with stop on dime changes, unhinged rhythms, and angular riffage, so y'all should eat this shit up.

"The Den" drops this spring via Bandcamp.

Best of 2018: Leftovers Edition

I know our original list was pretty comprehensive, but we're not finished yet. Here is some more good shit from 2018 that you may have missed, some of which we forgot entirely. Additionally, some of these aren't necessarily mathcore*, just some good music we liked that came out last year, OK? Alright then.

*we here at Mathcore Index like to keep it eclectic, so brace yourself if you're expecting absolutely no crossover.

Best of 2018

Mathcore Index's Best of 2018


There were so many incredible releases this year I was having a bit of anxiety about leaving some stuff out, so apart from my top 10 full-lengths I also did a comprehensive roundup of EPs and honorable mentions that I believe deserve just as much attention as the LPs listed below. Finally, this list was determined by a combination of Bandcamp, Spotify, and (go ahead and laugh, charted 10+ years of listening) and naturally my level of enjoyment, so rest assured your boy gave this a lot of thought. Let's go.
