Michelle Dorrance’s extraordinary rhythm-dance concerts owe a lot to the ensemble—each dancer a genius in her own way. For The Center Will Not Hold (yes, after the doomful Yeats poem) that collective power is both method and message. Co-choreographed by Dorrance and her longtime buddy, hip-hopper Ephrat Asherie, the hour-long piece begins with a panoply of solos. Besides tap and hip-hop, they feature Detroit jit, House, Chicago footwork, Memphis jookin’, body percussion, litefeet—an American landscape. At first the performers are isolated: one at a time, a bright spot of rhythm and motion in prevailing darkness. But eventually the darkness dissolves and the dancers rejoice together, as if Yeats’s “rough beast” were reveling in its conglomerate nature. With live music by Michelle’s brother Donovan Dorrance, The Center Will Not Hold is a family affair—blood and otherwise. —Apollinaire Scherr
