Dawn Chorus is a sound piece in which urban noises are transformed into birdsong. The artist takes field recordings of urban sounds, such as traffic and building sites, and uses them as the input for music recognition software, using the midi bird tweet setting.The sounds emanate from small boxes, which intermittently play ten second bursts of 'birdsong'.The nesting boxes hint at attempts to reintroduce something lost, while the sounds,sanitised sound bites of noise pollution, are appropriately enough experienced within the quasi natural environment of an ersatz jungle.
