Organization
The International Composers' Guild was an organization created in 1921 by Edgard Varèse and Carlos Salzedo. It was responsible for performances and premieres of works by Béla Bartók, Alban Berg, Erik Satie, Carlos Chávez, Henry Cowell, Charles Ives, Maurice Ravel, Wallingford Riegger, Francis Poulenc, and Anton von Webern, and others.
Management of the ICG.
The Guild was run by a Council consisting of:
However, in practice most of the work was done by Edgar and Louise Varèse and Salzedo. However following the First season Claire Raphael Reis was appointed executive secretary of the guild. Once in post she was able to relocate the second season to the Broadway based Klaw Theatre, which had a capacity of 805. After hosting the American premiere of Arnold Schoenberg's Pierrot Lunaire on 4 February 1923, she proposed staging a repeat performance, contrary to a rule of the ICG emanating from Edgard Varèse that aside from an immediate encore, no musical piece should be scheduled by the ICG twice. Later that year she motivated several members to secede from the ICG to found the League of Composers. The ICG then relocated to the broadway based Vanderbilt Theatre for the third season and to the Aeolian Hall for the last three seasons.
