interbellum is an audiovisual collective consisting of the musicians and instrument builders Nathan Marcus and Loden Rietveld and theatre designers Malou Palmboom and Aimée Gersons, based in Utrecht, the Netherlands. The collective creates immersive audiovisual performances and carefully constructed dreamscapes.


interbellum’s newest project “symbiotic interlude” explores how nature and technology meet. How do these seemingly opposite entities connect and what do natural and technological systems have in common? Join us in our alternative reality where rugged rainforests meet cable clutter and fireflies move to electronic music.
