Yorke collaborated with Modeselektor on their most recent album Monkeytown, from which both tracks were taken, and their previous album Happy Birthday, where he contributed vocals to the track 'The White Flash'.
Radiohead played a two-hour headlining show on Saturday night to a packed crowd at the event. They first headlined the California festival in 2004.
After the show, Yorke DJed until 4am at a hotel in Palm Springs for an intimate group of friends and family.
Radiohead will tour Europe this autumn for their album King of Limbs, and will play a trio of dates in the UK, as well as beginning their first Australian tour in eight years this November.
