Where did the creator of "International Composers' Guild" spend the greater part of his career?
Edgard Varèse Edgard Victor Achille Charles Varèse (] ; also spelled Edgar Varèse; December 22, 1883 – November 6, 1965) was a French-born composer who spent the greater part of his career in the United States.
Gustav Mahler Gustav Mahler (] ; 7 July 1860, Kaliště, Bohemia, now Czech Republic – 18 May 1911, Vienna, Austria-Hungary) was an Austrian late-Romantic composer, and one of the leading conductors of his generation. As a composer he acted as a bridge between the 19th century Austro-German tradition and the modernism of the early 20th century. While in his lifetime his status as a conductor was established beyond question, his own music gained wide popularity only after periods of relative neglect which included a ban on its performance in much of Europe during the Nazi era. After 1945 his compositions were rediscovered and championed by a new generation of listeners; Mahler then became one of the most frequently performed and recorded of all composers, a position he has sustained into the 21st century.
