Gerhard Eckel: electro-dynamic feedback system Karlheinz Essl: modular electronics with resonators Recorded live at Studio kHz on March 31, 2026 https://www.essl.at/div/rhibozom.html YouTube video: https://youtu.be/EhgA_eu_92E rhibozom is a duo of Karlheinz Essl and Gerhard Eckel working at the intersection of electrodynamic feedback, analog synthesis, and shared physical instrument-making. Gerhard Eckel performs on an electrodynamic instrument played with ferromagnetic objects that act as resonators, modulators, and sound sources within the instrument's pickup and speaker field. Karlheinz Essl performs on a compact modular synthesizer, its sounds projected through a separate loudspeaker on the shared table. Both performers place, move, dampen, and excite the resonating objects — the handling of physical material is a joint practice, not divided by instrument.
