Thousands of people came ready to dance at Disclosure's set: Their debut album, Settle, made a lot of friends last year. But brothers Guy and Howard Lawrence weren't quite ready to host a rave: they kept pausing between songs and saying things like "Coachella, this next song is called 'You and Me.'" They both had drum kits to play, as if they were trying to prove that they weren't just checking Twitter onstage. But the show worked anyway, because it's impossible not to dance to songs like "When a Fire Starts to Burn." And it didn't hurt that their surprise guest on "F for You" was Mary J. Blige.
