Halloween 2026 in Paris: the Error Festival takes over Petit Bain for a techno night

There will be zombies, witches and perhaps a few unicorns, but this time they should mainly be pulling their weight on the dance floor. For Halloween 2026 in Paris, the Error Festival takes over at the Petit Bain, the renowned floating cultural venue moored at the foot of the Bibliothèque nationale de France. The idea? To bring together for ten hours techno, EBM and industrial music in a single floating space, with an international lineup that fully embraces its love for dark atmospheres and machine-like rhythms. The event is set for Saturday, October 31, from 8 p.m. to 6 a.m.

Three decades of industrial nights behind this Halloween party

This edition doesn’t just celebrate Halloween. It also marks the 30th anniversary of Yb70, hailed by the organizers as a cornerstone of France’s industrial techno scene, notably through the Seppuku and Parazit nights. To mark these electrifying milestones, the Error Festival brings together around ten French and international projects in the cargo hold of the Petit Bain.

The lineup features Sonic Area, Subtencia, Antechamber, Katran, Weever, Duellist, Mind Matter, Iszoloscope, Panzer and K.Oz. Antechamber and Duellist are also scheduled to perform in Paris for the first time on this occasion.

As for the dress code, monsters, freaks, fluorescent ravers, goths, zombies, witches, clowns and other creatures are welcome: a sartorial freedom that doesn’t force you to choose between looks and costumes. A barge moored on the Seine, ten hours of dark electronic music... the Error Festival ticks a few boxes for those seeking a Halloween techno night in Paris where the undead, for once, have no excuse to stay still.
