OntheFloor at Ace Hotel (slide show)

The Breslin and the Dance Cartel teamed up to create OntheFloor, a show-party mashup choreographed by Ani Taj and staged in the ultrahip Ace Hotel's subterranean Liberty Hall. The sweaty affair is perfect for warming up on frosty midweek winter nights—but be sure to go soon. OntheFloor is out the door on December 18.
