This kinetic sound installation and live performance instrument is based on the Leslie rotary speaker used in the 1960s-70s to create early stereo vibrato effects, notably with the Hammond organ. The system is powered by direct, fluctuating audio voltage and bass frequencies which govern the speed at which the horn spins, creating an uncanny pattern of sound frequencies with stereo modulations and spatial sonic reflections. The sounds played through the horn are composed from field recordings made at the former Mungo Scott Silo complex in Summer Hill, Sydney. untitledbrown.zina.org wooloo.org/artists/1878 festivalofmosman.net/2011/events/barricade-radio-middle-head-2011
