Pauline Oliveros figured prominently in the Express’ Fall Arts Guide feature on the local avant-garde, notably for her involvement in the San Francisco Tape Music Center. The 1960s collective relished institutional autonomy and worked at the intersection of technology and innovative composition, a characterization befitting local experimentalists today. Her early work, such as “Bye Bye Butterfly,” which employed oscillators, manual tape delay, and a recording of Puccini’s opera Madame Butterfly, jettisoned past themes and conventions in favor of electro-acoustic manipulation. Much of her work since has involved a meditative approach to perceiving sound known by her coinage as “deep listening,” and Oliveros continues to lecture at Mills College (She was the first director of its music department in 1965). In May, an installation entitled Deep Listening Room manipulated the sounds of its setting — the Whitney Biennial — in real time to focus attendees on the autonomic function of hearing. As part of the Berkeley Art Museum’s L@TE series (2626 Bancroft Way), Oliveros will perform with the local Thingamajigs Performance Group on Friday.
