Simone Dinnerstein anchors New Work for Goldberg Variations from center stage, where she plays Bach’s familiar score from a glossy black piano, while the dancers—five women, one man, all frequent collaborators of Tanowitz’s—join her in gauzy tunics and pants from the costume designers Reid Bartelme and Harriet Jung. Brushed vertically in dusty blues, yellows, and reds, their attire recalls ribbon candy. As they dart behind the piano, lunge upstage, and form, then disband, a constellation of partnerships, the lighting design by Davison Scandrett casts their movements in bursts of vivid ruby and lemon.
