The weekend of March 27-28, 2009, soon-to-be-sweaty throngs looking to dance will make their annual bee-line to Miami for the Ultra Music Festival. The 11th annual Ultra fest goes down at the city's Bicentennial Park, bringing with it performances from Bloc Party, Cut Copy, Santogold, Crystal Castles, Simian Mobile Disco, Hercules & Love Affair, Roni Size & Reprazent (in their first Stateside appearance in seven years), the Presets, Busy P, the Ting Tings, Deadmau5, and Tiesto. In addition to performing twice, Carl Cox will host a "Carl Cox and Friends" arena with an ultrasecret group of as-yet-unannounced special guests.
