Is a kinetic sound sculpture created by Peter Kutin in 2018.
It is based on the amplification of a unique rotating quadraphonic feedback setup.

Premiered in October 2018 at Unsafe+Sounds Festival


Four 100V speakers rotate on a 2.5m long horizontal axis. The structure resembles the klopotec – a type of bird-scaring windmill found in central Europe – from which Kutin drew inspiration.

By amplifying these rotating speakers, the emitted sonic signals and feedback travel within the space in an unfamiliar, yet strange and multidimensional manner. The sounds have been designed specifically for this unique system; to maximise its psychoacoustic effects. Static microphones simultaneously transmit the sculpture’s movement via a much larger quadraphonic PA system setup to surround the audience. The sonic movements can be perceived both horizontally and vertically at once, creating a wholly unorthodox new listening experience. Rotation speed, acceleration, and amount of feedback are the key parameters for this instrument, immediately structuring the space and seducing the listener. Bizarre movements of sonic fractals, feedback-patterns, and noise bursts provoke otoacoustic emissions and other auditory illusions emanating from within the ear of the listener itself. Flanked by flickering and pulsating lights, TORSO reaches lucid and hallucinatory heights. Visitors have described the concert experience as like exposure to an “expanded Dreamachine” – referring to the influential stroboscopic flicker device first developed by artist Brion Gysin.
