Through the themes of Saint-Saëns (The Swan, Aviary, Fossils or Aquarium) the whole history of jazz is revisited. Each animal has its own instrument and style: blues, bebop, swing, free jazz, fanfare… Between rewrites, adaptations and additions of compositions, the score lets different colours and sounds shine through. The trumpets cackle, the trombones roar, the saxophones squeal! To tell the story, a hungry wolf invites himself into the middle of this menagerie.
