This one's a little late, but oh well.
I saw 311 with Matisyahu and the Dirty Heads on Aug 26. Really a great show, full of energy. And Chad Sexton's drum solo was pretty sweet, ESPECIALLY when he coordinated the rest of the band in to a drumline! AGH! I've been wanting to see 311 for years; I don't care if you don't like 'em, fuck you!
And Matisyahu was a great bonus, in which I'd of been happy seeing him alone, really great live! Blew my mind!
