All Under One Magnetosphere

Electromagnetic waves fill the universe, radiating from solar storms and bursts of lightning, but also from our electronic devices and infrastructures. Using simple, DIY tools, a community of audio enthusiasts translates these waves into sound, uncovering hidden sonic worlds.

Five dedicated ‘natural radio’ enthusiasts venture beyond the electromagnetic pollution of the city, tuning into the Earth’s natural static to reveal a rich, textured soundscape, rarely heard.

Stephen McGreevy, a cult figure within this practice, shares stories of his recordings during the geomagnetic storm of 1989. Hannah Kemp-Welch travels to northern Norway in search of the electromagnetic waves of the aurora borealis, struggling to escape the omnipresent hum of the mains power grid. Alyssa Moxley captures the crackles of shooting stars in southern France. Matt Parker ventures into the National Radio Quiet Zone in Virginia, USA. And Anonea experiments with antennas from a remote location in northern Spain.

This audio feature encourages listeners to contemplate the vast, often invisible role electromagnetism plays in our daily lives. It invites us to look up at the sky and imagine radio waves bouncing off layers of the atmosphere, connecting us all under one magnetosphere.
