The Coachella Valley Music & Arts Festival draws dozens of bands, a couple hundred thousand fans and a passel of celebrities to the edge of the Mojave Desert every April, and this weekend the ritual is repeating itself.

The biggest headliners -- Arcade Fire, Kanye West, The Strokes -- are yet to perform; their sets are scheduled for Saturday and Sunday nights, and they'll probably bring out a good-sized crop of celebs. But several famous names are in for the whole weekend, including Katy Perry, who took in the Sleigh Bells' set on Friday night (April 15).
