Sub Rosa presents Pauline Oliveros' early and definitive tape and electronic music of the late fifties and sixties -- all released for the first time ever! Born in Texas in 1932, Pauline Oliveros is more than ever an important American composer. Her accomplishments speak to an array of disciplines: her pieces for accordion; the creation of the Deep Listening Institute, a center dedicated to fostering artistic creativity through workshops, performances, and new technologies; her approach to improvisation in relation to meditation; and her numerous and varied collaborations with, among others, John Cage, Morton Subotnick, Terry Riley, Sonic Youth, Erold and Andrew Deutsch. Each piece on this release exemplifies her systematic exploration of electronic sounds, which was fundamental to this period. "Mnemonics" prefigures her meditative and breathing pieces. "V of IV" structures sound as noise. "Time Perspectives" is among her first variations on silence. Finally, "Once Again" develops a wild energy that out-strips itself, a frenzy the likes of which is hard to find even to this day. As Oliveros explains, the detailed methodology behind her work offers a unique inquiry into the process of artistic invention itself. "My work with electronic music began in 1959. My first tape piece was an ambitious four channel work called 'Time Perspectives.' The piece was made by recording small sounds from objects resonated on a wooden wall and changing the tape speed. I used cardboard tubes as filters by inserting the mic into the tube and recording sources through the tubes. I used my bath tub as a reverberation chamber. Sections of the piece were improvised and then subjected to speed changes. When the San Francisco Tape Music Center was established together with Ramon Sender and Morton Subotnik there was a pool of equipment to use and I began to work with electronic sound. Rather than cut and splice small pieces of tape together to make a composition I chose to work in real time. I used two tape machines with the tape running across both machines to make a delay system. I used two or more oscillators at high frequencies to produce different tones. These tones would also interact with the bias frequencies of the tape recorders. I would play the oscillators into the tape recorders improvising my way through the piece. My system of composing in this manner was my own invention.
