I've been listening to a lot of Say Hi lately. They're a band, but the music is recorded almost entirely by Eric Elbogen... and it's great. If you're not familiar, I highly recommend starting with their latest CD "Ooh's & Aahs" and seek out their older stuff after that. The track that starts this weeks playlist is from their 2008 disk "The Wishes and the Glitch". It's all worth checking out - especially since you can find it on eMusic.
Another gem: Lasso by Phoenix. Their new CD just came out and I'm already excited for the next one... though that will probably be a few years from now.
