Outsider music: classics of American classical music (56) - William Schuman - New England Triptych (1956) William Schuman, New England Tryptich A child of Hindemith's neoclassicism (thus austere music, rhythmically bold and not easily digestible), Schuman was probably one of the best American symphonists and orchestrators of the 20th century, as well as one of my absolute favorites. Also well-known as an "arts administrator," he was the head of the Juilliard High School and later president of the Lincoln Center for the Performing Arts, helping many young American composers.
