Greetings! Just joined up today so this is my first reply. I have never played Clair de Lune, but I thoroughly enjoyed playing an obscure Debussy piece called Ballad. I would consider it a major work, and it also sounds that way, but it is not as difficult as many Liszt pieces and things on that level... It is VERY impressionistic sounding... And very beautiful. As you probably already know, it sounds like crap on CD or on the computer--even more than usual, so try to listen past that. As Earl Wild says, listening to classical music on CD is like having sex through the mail. Hope this helps!
