Hopefully, if you like the Neon Indian, you should like Caribou. His album got a lot of raves as one of the best of 2010.

Dom's getting a lot of mention. He recently collaborated with Gucci Mane, of all artists. This song was the jam of my summer.

And Toro y Moi has changed up his sound. It used to be a lot more laid-back, but he added a full backing band, so now it's very funky and danceable. I'm loving "Still Sound." I was at this performance and danced my tooshie off.
