Debussy's

Debussy's Prelude to the Afternoon of a Faun and the poem which it is based on share a dreamy, ethereal, but nonetheless passionate feel.

There's an allusion to one of Debussy's works in that song.

I bought an mp3 copy of Debussy's "Clair de Lune" in an online music store.

Debussy's music makes heavy use of extended chords.

Clair de lune is the third and most famous movement of Debussy's Suite bergamasque.
