Subotnick’s work made an indelible impact on the future of music. He composed the first album of electronic music commissioned by a label, called Silver Apples of the Moon. He co-founded the San Francisco Tape Music Center, which held the first performance of Terry Riley’s “In C,” frequently considered the first minimalist music piece (in which Subotnick performed). He also started the California Institute of the Arts and helped design the Buchula 100, one of the first voltage-controlled synthesizers. These accomplishments would go on to influence a wide array of music and institutions, including the Lafayette Electronic Arts Festival, where a ninety-year-old Subotnick will play on Sunday, April 30.
