Sarah Kenchington lives on a farm in the Campsies, and for the past 10 years has been developing an elaborate and constantly evolving semi mechanical orchestra. Made from strictly human powered, mechanically assisted, acoustic instruments, this orchestra is designed to be played by one person and creates music that is dictated, in part, by the uncontrollable nature of the instruments in this set up. These include a pedal powered double ended hurdy gurdy/banjo, a pyramid structure that plays crystal glasses, a mechanical sequencer, and a brass band section which uses balloon membranes.
