Where do we dance? is a mobile and immersive installation that reactivates forgotten urban spaces as an act of resistance against the disappearance of venues for dancing and celebration. Faced with a 47% drop in nightlife venues in Switzerland between 2013 and 2023, and the closures linked to Geneva's PAV urban redevelopment, the project reclaims public spaces to fill them with music and light. Made up of a DJ/VJ setup, a sound system and a lighting device, it can be deployed in about ten minutes and produces a synesthetic experience where sound, light and dancing bodies merge. Drawing on the legacy of the Maddox Club, a space of resistance born under the Francoist dictatorship, it affirms that dancing together is an act of liberation physical, emotional and collective. Modular and evolving, the project is open to emerging artists and can adapt to future contexts of resistance against the erasure of nightlife culture.
