Mathcore Index

Promoting underground music since 2009

[Mathcore Index @Mathcoreindex]

The Dillinger Escape Plan live at Virgin Megstore, New York City, 1/20/2005. Vocalist Greg Puciato head walks during the opening of “Sugar Coated Sour,” easily one of the craziest moments in mathcore history.

Although Hot Damn! was my intro to the band, I must admit that THIS was my album. Lifted so many goddamn riffs from this thing.

RIP Andy Williams, thank you for all the music. Cannot imagine some of my most formative years without Every Time I Die.
