George Johann Carl Antheil was an American avant-garde composer, pianist, author, and inventor whose modernist musical compositions explored the sounds – musical, industrial, and mechanical – of the early 20th century. Spending much of the 1920s in Europe, Antheil returned to the United States in the 1930s, and thereafter composed music for films, and eventually, television. As a result of this work, his style became more tonal. A man of diverse interests and talents, Antheil was constantly reinventing himself. He wrote magazine articles, an autobiography, a mystery novel, and newspaper and music columns.

Leopold Anthony Stokowski was a British-born American conductor. One of the leading conductors of the early and mid-20th century, he is best known for his long association with the Philadelphia Orchestra. He was especially noted for his free-hand conducting style that spurned the traditional baton and for obtaining a characteristically sumptuous sound from the orchestras he directed.
