*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, contary to earlier CD glitch experiments from eg. Oval and Yasunao Tone that dealt with preexisting 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.
