Christian Wolff is now the sole living composer from the New York School of composition from the middle of the 20th century, a group that included John Cage, Morton Feldman, and Earle Brown. Wolff explores chance and detailed sonic events in his 17-minute In Winter 2 from 2024. Five performance scores are needed for performance. The score is marked for Ursula Oppens and the Cassatt Quartet, and Sally Pinkas and the Apple Hill Quartet.
