The Gwar-BQ of 2014 was utter and complete chaos. They expected 5-6 thousand people, what they got was over 11 thousand screaming metalheads.
The ran out of food.
The ran out of beer (not that I drink)
They ran out of soda.
They ran out of water.
But they didn't run out of insanity. Witness the following band: Eat the Turnbuckle. EtT are a wrestling-themed thrash band who flail around and smash each other with various things, doors, chairs, etc. The music is energetic and the fans are into it, but the blood they spill from each other is real.
Like I said, insanity. Can't wait to go back next year.
