To celebrate the inauguration of the newly restored former organ of the Palais du Trocadéro and Palais de Chaillot in Paris, the Orchestre National de Lyon and their organist–in–residence, Vincent Warnier, present two major works for organ and orchestra by Camille Saint–Saëns. Both are historically linked with the great Cavaillé–Coll organs, and are performed here together with an arrangement for solo organ of his famous Danse macabre.
