Combining ballets by four different choreographers, Ratmansky's Concerto DSCH is alternately tender and comedic, Tanner's Sonatas and Interludes is angular and contemporary, and Balanchine's Tschaikovsky Suite No. 3 is at first lyrical then ends with a classically brilliant finale. New to the NYC stage this spring, Soloist Justin Peck's first ballet for the Company, In Creases, rounds out the program.
