Music always appears in waves. Air, water, even seemingly solid bodies resonate, only empty space makes sound impossible. The musicians around composer and pianist Thierry Pécou flood the grotto, which is hidden behind a water basin on the Jubilee Terraces with tonal worlds of the incredible kind. Experience how Karheinz Stockhausen's minimalist notations create unrepeatable music for the moment. Feel the vibrations when the humpback whales sing and the energy waves of the tiger sun when it struggles with earth. Music as an elementary sound experience. It opens the ears and the mind, touches the gut and the soul. Deeply. The result: freedom and happiness.
