I've never seen them live before, don't listen to them often (although I do like them), and ended up going at the last minute, but I thought it was a really good show. Having no expectations probably helped. But I thought the energy was good and I didn't get bored at any point.
However, I would like to take this opportunity to bitch about the people around me who a) sang along louder than the band (although one guy was pretty nice when I asked him to dial it down, which I've never done before, but man, he was loud) and b) loudly talked the entire damn time -- during the quiet songs, the energetic songs, in between songs. Granted, they were mostly talking about the band's songs and not something stupid and unrelated, but still. You loud people suck.
