Mathcore Index

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.

What heavy music needs now more than ever is for fests curated by people with their hands in actual DIY spaces to get as much support as possible. The trend of too much nostalgia and letting corporations get involved prevents growth. We can’t let every fest become the same fest.

Holy scripture from 2010, still crack into this mfer occasionally whether I’m working on two handed tapping or needing some outside-the-box inspiration
