In this multi-sensory installation, live sound is transposed to infrasonic frequencies by a customized Pure Data program. This transformation generates visual and sonic variations through the oscillation of fine ball chains that drop from the center of multiple suspended speakers. As the chains make contact with the floor, their movements carve imprints into piles of sand. The resulting sounds mingle with those of viewers and peripheral ambient noise to create a causal loop of co-responsive activity with limitless variation. In this way, the work renders the immateriality of sound as a tangible event by silencing and reinterpreting the data of everyday life.
