The San Francisco Tape Music Center, or SFTMC, was founded in the summer of 1962  by composers Ramon Sender and Morton Subotnick as a collaborative, "non profit corporation developed and maintained" by local composers working with tape recorders and other novel compositional technologies, which functioned both as an electronic music studio and concert venue.  Composer Pauline Oliveros,  artist Tony Martin and technician William Maginnis eventually joined the SFTMC.
The SFTMC was an active and important hub for experimental music and interdisciplinary art in the Bay Area from 1962 to 1966.
Before the SFTMC was officially established, it began as a small music studio built in the attic of the San Francisco Conservatory of Music by Ramon Sender in October 1961.  The studio was minimally equipped and housed little else than the conservatory's two-channel Ampex tape recorder, but Sender and fellow Sonics composers creatively explored the limitations of the studio by using contact microphones to augment their recordings in an experimental manner. 
The concert series that also paved the way to the creation of the SFTMC, titled Sonics, was organized by Sender and Pauline Oliveros, a fellow composition student of Robert Erickson. The first Sonics concert of December 1961 consisted of original tape compositions by Oliveros, Sender, Terry Riley and Philip Winsor as well as a collaborative live improvisations.   The sixth and last concert of the series took place on June 11, 1962. 
The premiere of Terry Riley's seminal minimalist composition In C was performed at (and organized by) the SFTMC on November 4 and 6, 1964. It was performed by Riley, Steve Reich, Jon Gibson, Pauline Oliveros, Stuart Dempster, Morton Subotnick, Warner Jepson and others, while Tony Martin operated the light show or "visual environment".
The SFTMC members, particularly Morton Subotnick, were instrumental in the creation of the Buchla analog modular synthesizer.
Over the course of four years, the SFTMC changed locations twice, first to 1537 Jones Street and then to 321 Divisadero Street, before the Rockefeller Foundation awarded a $200,000 grant to Mills College to bring the SFTMC to Mills and merge it with the Mills Performing Group, where it eventually became the Mills Tape Music Center. Pauline Oliveros, Tony Martin and William Maginnis collectively served as directors for the new center, which is now the Center for Contemporary Music (CCM).  
Electronic music is a genre of music that employs electronic musical instruments, digital instruments, or circuitry-based music technology in its creation. It includes both music made using electronic and electromechanical means. Pure electronic instruments depended entirely on circuitry-based sound generation, for instance using devices such as an electronic oscillator, theremin, or synthesizer. Electromechanical instruments can have mechanical parts such as strings, hammers, and electric elements including magnetic pickups, power amplifiers and loudspeakers. Such electromechanical devices include the telharmonium, Hammond organ, electric piano and the electric guitar.
Terrence Mitchell "Terry" Riley is an American composer and performing musician best known as a pioneer of the minimalist school of composition. Influenced by jazz and Indian classical music, his music became notable for its innovative use of repetition, tape music techniques, and delay systems. His best known works are the 1964 composition In C and the 1969 LP A Rainbow in Curved Air, both considered landmarks of minimalism and important influences on experimental music, rock, and contemporary electronic music.
Ambient music is a genre of music that emphasizes tone and atmosphere over traditional musical structure or rhythm. It may lack net composition, beat, or structured melody. It uses textural layers of sound that can reward both passive and active listening and encourage a sense of calm or contemplation. The genre is said to evoke an "atmospheric", "visual", or "unobtrusive" quality. Nature soundscapes may be included, and the sounds of acoustic instruments such as the piano, strings and flute may be emulated through a synthesizer.
Pauline Oliveros was an American composer, accordionist and a central figure in the development of post-war experimental and electronic music.
