A trio of classic dances by Balanchine joins a favorite from Alexei Ratmansky. Mozartiana, one of Balanchine’s late works, weaves an elegiac spell with its austerely beautiful black costuming and pellucid classical choreography. Two dances set to Stravinsky, the elegant, neoclassical Monumentum pro Gesualdo and the spiky, arrestingly unique Movements for Piano and Orchestra, always make for a stimulating pairing. And Ratmansky’s Concerto DSCH, set to a piano concerto by one of his favorite composers, Dmitri Shostakovich, ranks among the dancemaker’s most exuberant and energetic works.
