Repulsion + Dehumanized + Skullshitter + Lucid Terror

Repulsion, a grindcore band active on and off for three decades, has just one album to its name, 1989's Horrified. But that record's unrelenting onslaught—the extreme-metal equivalent of projectile vomit, and yes, in this case, that's a very good thing—has earned it a permanent place in the underground hall of fame. Live, the Hollywood-via–Flint, MI band is a turn-off-your-brain blast.
