Robert Moran: His first "city" piece, performed in San Francisco on August 20, 1969, was "39 Minutes for 39 Autos", written for 39 amplified auto horns, 78 auto headlights, 30 skyscrapers, two radio stations, one television station, a Moog synthesizer, an unspecified number of dancers, theatrical groups, searchlights, airplanes, and, according to "Baker's Biographical Dictionary, 100,000 people (leaving 615,674 others to tend to business.) The "stage" was the summit of Twin Peaks from which Moran, gazing down at the city, cued the auto horns and headlights and Margaret Fabrizio and her assistants performed an electronic score. While the net musical result was being broadcast by the television and radio stations, buildings throughout the city--the City Hall, the War Memorial Opera House, the Union Oil Tower, and the Coit Tower among them--became facades on which light shows were performed.
