Keith Holzman cut his teeth as a theater director and lighting designer in New York. In 1964 he joined Elektra Records, which his brother Jac formed back in 1950. Keith coordinated production of all the label’s releases and later ran Elektra’s spin-off classical label, Nonesuch. The label released albums by the Los Angeles Chamber Orchestra and soprano Teresa Stratas, as well as music based on emerging electronic instruments such as the Moog and Buchla synthesizers. These include “Silver Apples of the Moon” by Morton Subotnick in 1967, and the “Nonesuch Guide to Electronic Music”
