Beverly Hills, CA: Copley Galleries, 1948. First Edition. One of 500 copies issued. INSCRIBED by the author and artist on the front endpaper: “For Charlotte [Bebe] and Louis Barron. Cordially, Man Ray, Hollywood, 1949.” An exceptional avant-garde association. Around this time the Barrons were beginning to experiment with committing electronic sounds as music to magnetic tape, and were ultimately not only pioneers in that field, but its inventors. One year after the date of this inscription, they would compose their first piece, "Heavenly Menagerie," and they would go on to produce the first electronic film score, for the seminal 1956 science fiction film, "Forbidden Planet" (credited as "tonalities" rather than "music" at the time, due to union rules). The Barrons' earliest compositions were slow and laborious, as their early work preceded the digital age, and involved building circuits and tape splicing to create even the smallest sequences of sound. In the decades that followed, electronic composition has become a worldwide phenomenon in every musical category. A tremendous association between pioneers in two major fields of twentieth century artistic endeavor.
