Gnarles Barkley is a collaboration between Danger Mouse & Cee-Lo Green, and the single off their first album was the first digital-only single to hit #1 in the UK charts. There are going to be a lot of good bands at Coachella (duh), but I recommend checking these guys out if you get the chance.
And now back to... well, nothing's going on right now. Don't forget to check out The Tool Hotline if you're bored.
