It was one damn good festival. It was my first time seeing Cannibal Corpse live, and holy shit did they deliver. Slayer was pretty good too. They played about a hour and a half set, if I remember correctly. Maybe a little less 'cause Manson was headlining. (even though half the venue emptied out after Slayer finished haha) Didn't really care much to watch Trivium, so I couldn't tell you about their performance.
Take pictures and post them up!
