At Romainville’s metal sorting site, Courrèges' uniting vision meets the raw potential of a post-industrial landscape. The monolithic mirror installation suspended above the main stage operates as a solar panel and light distributor, capturing and redirecting natural sunlight to create ever-shifting reflections across the facility's metallic surfaces. This interplay between artificial and natural light creates a layered experience, where the rave’s energy evolves with the sun's trajectory. As daylight fades, the lighting design transitions from solar reflections to artificial interventions, using motorized spots and LED panels to maintain kinetic impact throughout the night.
