Piano at the End of a Poisoned Stream is created using audio and visual material collected from Bombay Beach located on the Salton Sea, USA, with New Zealand film and video artist Andrew Denton. Formed from a geographical rupture, then populated by humans and their need to extract materials, leisure, and property, the highly salinized and toxic waterway evokes a ghostly future narrative. It has been described as the most depressing place in California. Signs of the human and nonhuman now litter Bombay Beach. As a sonic artist, I became transfixed with the numerous objects scattered throughout this landscape: rusty metal objects sticking out of the ground, wooden refuse from dilapidated buildings, sections of concrete slab, plastic bags entangled and flapping in dead bushes, and a lone broken piano. Using contact microphones, I recorded the sonic textures and tones by tapping, plucking and playing these objects. Using the creative techniques of computer vision, sonification, convolution, and improvisation, this work combines the audiovisual material in a temporally dynamic aesthetic. The sonic triggering device is a series of bird-in-flight videos (Denton), which randomly triggers a large bank of audio files.
