Concrete Staircase (Descent)

02May10

This sound work consists of a Pure Data patch that uses a feedback delay system to modify an audio sample of a person descending a concrete staircase. At first, the sound is recognisable and rhythmic: the reverberations in the concrete stairwell are clearly audible. Slowly the sound begins to layer and slip out of synchronisation with itself, creating complex polyrhythms and mechanical drones. The act of walking down the staircase, through repetition and density, becomes the sound of some hellish crank-driven elevator descending downwards into the earth’s core. The noise continues to accumulate until, after five minutes, the pieces quickly goes silent. The sound of the space the piece is installed in can provide the remainder of the soundtrack.
