closed-loop vibration 7" lathe cut LP 2005
recorded in Auckland, New Zealand

contact microphones, aside from tools, correspond to a tactility that is heard as sound is captured from within matter and transmitted through the air. In closed-loop vibration, contact mics are used to reveal the audible resonances of otherwise inaudible or low frequency vibration. The sounds generated in this recording are the outcome of an environment I set up, similar to my sound installations, where I allowed the variables of feedback, objects, vibration to dictate the sound as I provided a control (volume, distance between objects and speakers, between speakers and contact mics). The sounds were all produced in real-time and what I recorded I did not manipulate through editing, keeping true to the raw physicality of the sound waves contained within the space.
