The artists enlisted for A Prelude to The Shed do not need to share the stage with anyone. The impressive roster of this free two-week teaser for the behemoth cultural centre to open next spring includes avant-garde ballet choreographer William Forsythe, R&B headliner Abra, social-interaction orchestrator Tino Sehgal, the Dream Ring of flex dancers, and Kunlé Adeyemi, architect of Prelude’s ingenious mini-Shed a block from the future Shed’s raw hull, in Manhattan’s burgeoning post-industrial strip north of the gallery district and south-west of Times Square.
