*50 copies limited edition* This CD is inscribed with physical defects (scratches with a needle) covering track 8 which consist of a 22049 Hz inaudible sinewave. This will produce audible artefacts, different in nature depending on the CD player used for playback. Tracks 1-6 are recordings of track 8 applying different forms of physical scratches. The results can be described as simple rhytmic studies, some surprisingly jazzy in nature. Timbre-wise only the pure artefacts are heard, contrary to earlier CD glitch experiments from eg. Oval and Yasunao Tone that dealt with pre-existing audio and data being manipulated by the damage to the media. The listener is encouraged to vary the playback of track 8 by forwarding and reversing playback and to further scratch the CD to explore the variations possible.
