Cicadas have settled in Brittany. Fake news? Or tangible sign of global warming? Are we still able to be sensitive to the warning signs around us? The sound installation «Chaud Change» calls the walkers of the Conservatoire botanique to think about environmental issues in a sensitive way from September 16 to October 2, 2022. As part of this installation, two sound naps will be proposed on Sunday, September 18 to invite to a poetic journey through the soundscapes crossed by the ears and microphones of Hughes Germain; from the Sahel to the salt marshes, from Taiwan to the Stang-Alar Valley. An ode to large spaces and small sounds, conducive to a moment of collective laziness, which invites the spectator to discover the new headquarters of the Botanical Conservatory.
