Call for performances: the 25 Hour Radio Relay returns - Worm - A Rotterdam based organisation working at the intersection of culture and arts.

A horizontal digital banner with yellow background and black lettering in two contrasting fonts advertising WORM's 25 Hour Radio Relay on 24-25 January 2026. Drawings of index fingers pressing a black button are under the main text. The main text states: 25 Hour Radio Relay. The cursive font states, Open Call.

The 25 Hour Radio Relay is back!

Over the weekend of 24-25 January 2026, we’ll set up multiple stages in our UBIK room for a live-to-air music and performance marathon, broadcasting non-stop for 25 hours from WORM. The audience is invited to show up, tune in, drop by…and even stay overnight for the full experience.

Radio WORM wants to hear your best and oddest ideas: your radio plays, game shows, acoustic performances, noise sets, interviews, poetry and spoken word, improv choirs, sermons, sound art, dawn choruses, audio essays, home-made instrument jams. Bring us your experimental gems.

Want to perform live?
Check out our tech guidelines and tell us about your idea in the proposal form.
Deadline 22 November.

Want to send a recorded item? Upload your mp3 files to the prerecord link and we’ll play Prerecord Roulette in between the live performances! Deadline 11 January.

In both categories, we’ll prioritise pieces that bring something experimental, niche, DIY, uncommon: the serious, the absurd, and the profoundly entertaining for both live audience and online listeners. Bands and DJ sets are not quite right for this occasion (but…try us?)

The audio broadcast will be archived on Radio WORM’s mixcloud. You can check out the highlights from 2025’s 25 Hour Radio Relay in photos and audio. Listen deeper, listen wider, listen weirder.
