Fan Recaps and Comments:

This was a particularly good concert. OK Go was a superb opening act, and the Johns had great energy that night. My favorite bit, next to the performance of Man, It's So Loud In Here which incorporated a disco-ball, was a party trick TMBG did. They piped an ordinary FM radio through the venue's sound system and turned the dial back and forth until the audience shouted stop. Then they proceeded to play along with whatever was on that station. It was a very impressive display of musical improv ability.
