3 way tie between Gallows, Andrew W.K., and Devin the Dude.
Gallows because when their set came up, they literally said "FUCK this stage" and moved all their gear INTO THE MOSH PIT before playing their full set there. For a few songs they even had a circle mosh going around them. When In the Belly of a Shark
played, the crowd fucking lost it. My buddy STILL has the scars to prove it 3 years later.
Andrew W.K. because I didn't think anything could get crazier than Gallows, but he proved me the fuck wrong. He played right after mc chris (who is awesome as well) and by the end of his set, there were more people on the stage with him than there were in the pit. Tons of stage dives, people literally hanging from the ceiling, plenty of moshing and bloodshed, and even some tits. Kick ass show.
And at Devin the Dude's last show here in Austin, me and a friend were actually hired to be his personal cameramen for the entire night. ALL access VIP fucking treatment. We even got to eject people from the club (seriously, stop touching the fucking $3,000 camera) and got to go backstage and drink infinite amounts of free liquor, bbq, and pizza. Plus, serious fucking gangster weed. I barely remember most of that night, but what I can recall is fucking amazing
What have you done lately? ;D
