We’re sure you’re all tired of seeing the latest and greatest “Harlem Shake” videos by now, but we couldn’t resist sharing this one. Our friends at Ultra decided to get in on the action with their own version of the viral dance. The video is pretty true to form: 30ish seconds, spastic dance moves, and appearances from people in nonsensical costumes. There are ballerinas, donkeys, clowns, and zombies but unlike the other versions this one has a very special dance music guest, Carl Cox. Press play and watch him wave a towel around in pure bliss.
