“1 Of IV” and “Big Mother Is Watching You” were both made in the summer of 1966 at the University of Toronto Electronic Music Studio. “1 Of IV” was previously released in 1967, on Odyssey, alongside works by 2 other young composers – “Come out” by Steve Reich and “Night music” by Richard Maxfield. “Big Mother…” is a previously unreleased piece. The 3rd (and final) piece on this compilation was made at the San Francisco Tape Music Center in 1965 and was first released in 1977 on the compilation New Music For Electronic And Recorded Media, released on 1750 Arch Records. The 3 pieces on this CD are all live experiments, which at the simplest level use either an array of oscillators and filters, a mixer and one spool of tape feeding a series of (variously set up) stereo tape machines. Long delay lines, pile ups of noise and rich sonorities are the stuff of this music. The third piece also uses samples taken from Pucini’s Madame Butterfly. All 3 pieces on this CD are not included on the 12 CD boxset of early electronic music by Oliveros, released by Important Records.
