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. In Wolff’s 16-minute Trio XIV for tenor saxophone, percussion, and piano, the unpitched percussion are picked from skin-drums, metal, junk, and other sources. The pitched percussion are the player's choice. Multiple performance scores are used in performance.
