Walking on the esplanade of La Défense, surrounded by art pieces and skyscrapers during the day, feels one way. Equipped with headphones and a small lamp, descending into the abyssal darkness of the Parisian business district’s underground creates a completely different atmosphere. This is what visitors experience at the exhibition “Sous l’horizon” organized by Sara Dufour and Lauranne Germond from the COAL association, which blends art and ecology. Imagine being deep under the sea, where light no longer reaches and sounds blend with your heartbeat. In this immersive experience, guided by Emile Loizeau’s voice and Mariette Navarro’s text, visitors come into contact with the beating heart of an imaginary amphibian by Antoine Bertin or the various fluorescent-phosphorescent creatures by Ugo Schiavi. They explore the bacto-luminescent cosmos of Jérémie Brugidou and lose themselves in the nirvanic temple of Shivay La Multiple. This is the first event of the festival “Les Extatiques” dedicated to “other worlds”, through “Sous l’horizon” raising awareness about environmental issues in the underwater world.
