Mutoid Man drummer Ben Koller isn't an easy act to follow. Dude drums and has drummed in bands like All Pigs Must Die, Converge, Killer Be Killed, Cave In, and United Nations, though Slipknot's Jay Weinberg proved himself worthy to sit where Koller has sat.
Weinberg joined Mutoid Man on stage in Nashville, TN on November 8 to play "Gnarcissist," and of course he crushed it. You can also see Koller in the background doing some backup vocals behind Weinberg!
