Amériques

Amériques is an orchestral composition by Edgard Varèse, scored for a very large, romantic orchestra with additional percussion (for eleven performers) including sirens. Written between 1918 and 1921 and revised in 1929, it was the first work Varèse composed after he moved to the United States. Although it was not his first work, he destroyed many of his earlier pieces, effectively making Amériques his opus one (although he never used that designation).
