Ratmansky's widely acclaimed Concerto DSCH features playful allegro sections and tender moments. Tanner's Sonatas and Interludes is an angular five-part pas de deux. New this season, Soloist Justin Peck's In Creases includes two onstage pianos and a score by Phillip Glass, and serving as a rousing finale is a Balanchine favorite: the all-American Stars and Stripes.
