The Dodos are great. I saw them at DC9 on Sunday and I really enjoyed their set.
I agree on the assessment of The Big Sleep. The female singer is terrible. There are okay for about 2-3 songs and then get a little tiresome. It seems like they play in DC a lot.
I'll be at the show, mainly to see The Dodos again. I am not sure how I feel about Les Savy Fav, however, they look entertainling live (based on videos and YouTube). Worth it?
