Murs de l'Atlantique is a piece of research carried out around the Breton territory, setting up a visual dialogue between two phenomena: the remains of the Atlantic Wall — the blockhouses that stud the coastline, heavy and permanent — and the free parties, those illegal techno raves that appear spontaneously in the countryside and along the coast before vanishing just as fast. Walls of sound, fortified enclosures, improvised encampments, the radicality of materials, sounds and elements: the project is concerned with ways of occupying space — the margins, in this case — with architecture, whether unalterable or on the contrary rudimentary, and with the party read as a guerrilla operation, a breach outside any categorisation and any control.
