It's Saturday—time for another day of superior DJs and performers in MoMA PS1's courtyard. Today's music will be fabulous, with the Border Community label's James Holden jetting in from London to play his ethereal, almost diaphanous version of techno. (Even if he pumps it up a bit for Warm Up's massive crowd, it should still be amazing.) Germany's Kassem Mosse purveys a pleasingly deep sound that slides along the house-techno-dubstep spectrum. London's talented Om Unit and Texan synth duo Silent Diane handle the early sets.
