With his fingertips, the artist Chassol awakens the sleeping nave of the Musée d'Orsay, a fabulous setting for Cavelier's Sleeping Penelope. The brilliant pianist presents "Ultrabirdz" in live session, an enchanting original creation, consisting of tracks from his first album "Big Sun" and unreleased tracks.  In the middle of a forest of statues and screens, the naturalist musician engages in a melodic dialogue with the birds of his native island Martinique.

The performance "Ultrabirdz" echoes the exhibition "The origins of the world. The invention of nature in the nineteenth century", questioning the artists' relationship to nature through their construction and their construction of their vision of it. It opens the series of digital creations around music and the arts entitled #OrsayLive.
