VORTEX 5

Electronic music (or " musique concrete") has been made possible by the development of magnetic tape recording. This new art form is now being practiced in almost every country in the world. Leading contemporary composers (such as Boulez, Krenek, and Varese) have turned their attention to the musical possibilities of tape. In this, its fifth season, Vortex is bringing the Bay Area a definitive selection of the best compositions in this field, many of which were recently premiered in the Experimental Music Festival at the Brussels World Fair. A unique and distinguishing feature of Vortex is the accompaniment of visual non-objective projections throughout the program.

THE COMPOSERS

GORDON LONGFELLOW, a Californian, is in his late twenties. Before joining the Ampex Corporation, in 1953, he worked as a professional popular pianist and singer. He became interested in the possibilities of magnetic tape for musical composition after attending the first Vortex demonstration. Since then, Mr. Longfellow has been active as a composer and experimenter in the field. "350 Dash Two" was premiered at Vortex 4 and later featured in the Vortex presentation at Brussels. In this work, Mr. Longfellow a d (?JH) rotational playback possibilities for metallic sounds in different pitches.

DAVID TALCOTT was born in California in 1938. a musician and electronics engineer, he has been associated with radio station KPFA for five or six years. At KPFA Talcott has engineered and produced numerous dramatic programs. He has also been an important figure, both technically and creatively, in the vortex demonstrations. His earlier works, "Trilogy", "Loop Number 3" and "Piano and Piano" have clearly established Talcott as a skillful and talented composer. "Tribulation 1958" premiered by Vortex at the Brussels Fair, is this artist's most ambitious and complex work, in which he combines piano and synthetic sounds.

The Vortex demonstrations are sponsored by the Audio-Visual Research Foundation with the cooperation of the Morrison Planetarium. The Foundation is organized to explore the esthetic possibilities of technological developments in auditory and visual media. Our first project, Vortex, stems directly from this approach.

Technically Vortex utilizes all known systems of projection, along with one of the most highly developed sound playback systems extant. Yet, it is a live creation of sound and image, being performed for a specific audience. Vortex is based on a mutual complement of aural and visual elements, in which they reveal unspoken meanings about one another which exist in neither alone. Having presented successful Vortex series in San Francisco and Brussels, the Foundation hopes to give demonstrations in Tokyo and Moscow in 1959.
