I've done listened to one of their albums all the way through. I probably haven't even really listened to more than a small handful of songs before.
It's, probably inevitably, Goo that I've got on. It's more of a racket than I thought it was going to be, in a good way. I thought they'd be one of those bands who were noisy and innovative at the time but whose past albums have dated and now sound a little lame, but I think I'm being proven wrong.
What else should I check out by them?
