yeah, for our show (minneapolis) fall out boy came out a little bit weak but then picked it up and actually sounded pretty good. but, i will never go to see MCR again unless they're on a tour like Warped with many other bands. it was such a waste.. they're horrible live. i went to Taste of Chaos in Philadelphia and they sucked so bad. skipping entire verses and leaving out other parts here and there and the sound was mixed really bad. same thing for warped.
but yeah i agree, atreyu kicked ass, they surprised me, i thought they'd be worse live. Hawthorne Heights and Senses Fail were freakin incredible.
I'd say that other than the obvious main stage bands, the ones that really kicked ass were on the SmartPunk and Ernie Ball stages. Bleed the Dream, Emery, Boys' Night Out, Split Habit, Opiate for the Masses, Hopesfall.. One that really surprised me was The Matches.. after hearing/seeing them live, it's almost not even fun to listen to the CD anymore. they're so perfect live, and have so much more energy than the studio recording.
