For sure. The band I was in back in college played a show with them in Baltimore. Would have been 2002-ish. I'd never heard of them, and had never seen anything like it. Total insanity. At one point I remember the bass player breaking the head of his guitar off on some guy's head - total accident, he was just going crazy with it and hit this guy so hard that it broke right off. He must have had a string lock or something because everyone just carried on like it had never happened.
Saw them again a few years ago here with Darkest Hour and for how awesome I think they are, Dillinger's set was so much more over the top that it made Darkest Hour look like a bunch of school girls.
