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.
