Richard Maxfield专辑介绍：by "Blue" Gene Tyranny This is a good example of Oliveros' earlier electronic music using a configuration of tape recorders patched into each other with magnetic tape spliced in loops so that a form of "automatic generation" system was created by feedback. Similar to Richard Maxfield, Oliveros used bias frequencies of tape recorders and difference, or lower "ghost tones" produced by the interference of very high frequencies.
