Rude Mechanicals are excellent too. They just manage to balance novelty and avant garde surrealism; competent enough musically to get away with some of the odder tricks. I liked the bluesy tones, and they could drop into decent rock. Not quite sure the audience really responded to the performance-art side though.
Rome Burns weren't quite as good as I was expecting. I hadn't got around to seeing them until now, despite having listened to their album Done & Dusted fairly often. For people who've been around for a while and have an album out and stuff, I was surprised that they really deserved their position as opening act.
