CTM is excited to bring back repeat collaborators Emptyset for the world premiere of “Signal”, a radio-based performance working directly with ionospheric propagation as a live sonic sculptural process and compositional tool. Bouncing real-time radio broadcasts across the ionosphere to integrate atmospheric noise into an analogue signal chain, with “Signal” James Ginzburg and Paul Purgas examine the transmission of basic elemental sound sources and experiment with their ornamentation through external environmental and atmospheric conditions. In doing this they evoke the affective power of the atmosphere above and around us. Produced in collaboration with Deutschlandradio Kultur / Klangkunst, the project will be developed into an album release following its configuration as a live performance and will be broadcast via Deutschlandradio Kultur on April 17th.
In collaboration with Deutschlandradio Kultur Hörspiel/Klangkunst. With the kind support of Mediabroadcast GmbH.
