'Surfaces' is an edited selection of tracks from the performance 'Working Space / Surface Time' by John Court and Mark Roberts.
The sound sources used were generated entirely by the movements of Court's body as he moved slowly over a raised wooden platform. The sounds of his movements were picked up by four piezo microphones, amplified, and processed live. Each performance lasted exaclty 8 hours, and the material presented on this album was selected from four separate performances made during 2004.
The album contains 11 mp3 tracks edited into a continuous soundscape.
