Andrew WK...I had no idea live shows could be that fun. On CD it's just dumb party rock, but live it's the most fun I've ever had at a show
Yellowcard...a band I really don't like, but live they were very fun and got the crowd into it.
The opposite.
New Found Glory sucks badly live...didn't help that when I saw them they played all new songs that no one knew, and they kept waiting for fans to sing along
Panic! at the Disco...ok, they're fun live, but you can tell that the singer's voice benifits from studio magic.
