When she assumed the helm of Danspace Project at St. Mark’s Church in the East Village, in 2008, Judy Hussie-Taylor dispensed with the usual mode of programming and used Platforms instead. Taking after the most forward-thinking European art biennials, these Platforms have stretched a single theme over several months, with the usual evenings of dance supplemented by talks, all-day dance-ins, and other adventures in form. Most exciting, the artists themselves have been the curators. You begin to understand them more entirely. It’s fitting, then, that “Danspace @ 50: The Work Is Never Done. Sanctuary Always Needed” splits the difference between the usual retrospective and the usual season of premieres, with choreographers seminally associated with Danspace (Ishmael Houston-Jones, Donna Uchizono, Bebe Miller, Reggie Wilson, Blondell Cummings) refashioning early work for a new generation of dancers and viewers. As one youngish participant told Siobhan Burke of The New York Times, “It’s going to be crazy. It’s going to be history all over again.” Go to all of them, or any. —Apollinaire Scherr
