A monthly open-form radio series that progresses through live electronics, field recordings, and archival fragments. The title emerges from waves that remain imperceptible even as they are heard and felt. The series follows these signals as forms of vibration moving through aetheric conditions in bodies, environments, and infrastructural systems. Each episode moves between sonic essay, radio play, and live composition, tracing rupture, resistance, and repair within border zones, technological networks, and contested terrains.
