One of the things I picked up at the convention was an advertisement to this music festival called The Land of Nod. It looks really cool.
There are a bunch of bands playing there that I really want to see: of Montreal, Rasputina, the Eagles of Death Metal, and Murder by Death. Obviously, everyone's heard of Montreal and the Eagles of Death Metal. I know I've read about Rasptuina somewhere and Rory once mentioned that he loved Murder by Death.
There are even a few bands listed here that I've seen before but wouldn't mind seeing again, including My Dear Disco. I saw them about a year and a half ago and had a really good time. They were more funky than disco-y, actually, but that's not such a bad thing either.
