The Blue Spectrum
A Blue Spectrum piece is determined by the process, in which one or two tape recordings are mixed spontaneously with or without the addition of effects or instruments. In turn this recording is played back with effects and mixed with other tape recordings with the addition of instruments to create a final piece.
This source material us often reused to create new recordings.
Blue Spectrum has been compared to Fossils, a broken CD player and even John Cage.
