AEOLIAN RADIO is a recorded live performance built around a kinetic pendulum antenna, voice, field recordings, and live electronics. As the SDR antenna swings, it receives and disturbs radio signals, producing shifting rhythms of interference that Thrän and Samuel Hertz use as material for improvisation.
The 60-minute piece was recorded at the ONX NYC, through the invitation of Afroditi Psarra, who invited Collective Notes to be featured at Transmission Ecologies, Psarra’s monthly broadcast on STEGI RADIO.
The work treats listening as something bodily and relational. Performers and audience share a space shaped by movement, distance, signal, and static, becoming attentive to electromagnetic activity that normally remains outside perception. The piece asks how listening changes when human rhythm is placed in relation to signals, environments, and more-than-human forces.



Pendulum
Thrän's artistic focus lies at the intersection of visual arts, music, and experimental research. Their works reflect on ecological and social dimensions and always incorporate the diverse relationships between space and body.
