When Oliveros turned 21, she obtained her first tape recorder, which led to her creating her own electroacoustic pieces. The Center later moved to
Mills College, with Oliveros serving as its first director; there it was renamed the Center for Contemporary Music. In 1966, she attended a summer course in electronic music at the
University of Toronto, studying with
Hugh Le Caine. "I of IV", one of her most famous electronic pieces, was realized there; in 1967, it was released on LP by
Odyssey Records alongside works by
Richard Maxfield (
Night Music) and one-time San Francisco Tape Music Center associate
Steve Reich (
Come Out). Oliveros often improvised with the
Expanded Instrument System, an electronic
signal processing system she designed, in her performances and recordings. Oliveros held Honorary Doctorates in Music from the
University of Maryland, Baltimore County, Mills College, and
De Montfort University. In 1967, Oliveros left Mills to take a position at the
University of California, San Diego. She also studied karate under Ingber, achieving
black belt level. In 1973, Oliveros conducted studies at the university's one-year-old Center for Music Experiment; she served as the center's director from 1976 to 1979. In 1981, to escape creative constriction, she left her tenured position at UCSD and relocated to
upstate New York to become an independent composer, performer, and consultant. In 1987, Oliveros had the tuning of her accordion changed from
equal temperament to
just intonation. She sings and plays the retuned accordion (without electronics) in the 1993 opera
Agamemnon. Oliveros was a member of
Avatar Orchestra Metaverse, a global collaboration of composers, artists and musicians that approaches the virtual reality platform
Second Life as an instrument itself. ==Deep listening==
