Organ A major work for large organ, War and Peace was commissioned by the American Guild of Organists. The composer points out that "work on this piece began on the 50th Anniversary of Hiroshima," the final shot fired in the U.S. war with Japan. Foss describes the cycle of war and peace in three movements: I. Fear and Distress; II. Shots, and Explosions; III. Aftermath / Prayer.
