Amériques is a 1921 composition by Edgard Varèse, but it remained unperformed until 1926.
It was his first work composed in the United States, since he moved to the country in 1915 because of World War I. It was at the completion of this work that Varèse, along with Carlos Salzedo, founded the International Composers' Guild, dedicated to the performances of new compositions of both American and European composers. The ICG's manifesto in July 1921 included the statement that: "The present day composers refuse to die. They have realized the necessity of banding together and fighting for the right of each individual to secure a fair and free presentation of his work."
Zappa about "Amériques"
"I mean, a piece like "Amériques" by Edgard Varèse (...) would scare the average teenager to death. and I mean really scare 'em to death. Vanguard just released a recording of it.". - Zappa in Don Paulsen interviews FZ, 22 December 1966.
"I would recommend (...) the Utah Symphony recording of "Amériques' on Vanguard." (Edgard Varèse: The Idol of My Youth, June 1971)
