Petra Zélie is an experimental sound artist and filmmaker working across several bodies of work: feedback and contact-mic performance, granular composition, radio and transmission, and handmade electronic instruments. An ongoing strand she calls communing starts with the space itself. She captures a room's electromagnetic field and radio interference, then feeds it back live, channeling a site's particular haunting rather than composing over it. Her film The Yellow Wallpaper (2022) was featured in YELLOW: Beyond Van Gogh's Colour at the Van Gogh Museum, Amsterdam (2026).
