One of the twentieth century's most innovative and influential composers, Debussy was a musical impressionist (a term he disliked). Prélude à l'après-midi d'un faune draws inspiration from a poem by Stéphane Mallarmé, whilst La mer, a set of symphonic sketches, vividly depicts the relationship between the waves and wind of the open sea. Jeux, one of Debussy's final orchestral works, was written for Diaghilev and the Ballets Russes.
