One of my favorite composers is Claude Debussy. I recorded his piece “La cathédrale engloutie” [the swalowed/engulfed/sunken cathedral]. I hope you like it. Click the link below to listen to download the audio.
The piece tells the story of an ancient catheral that rises up out of the sea (or possibly a swamp or marsh). Debussy, in a truly impressionistic fashion, paints a picture of curch bells and an organ playing first above water, once the cathedral has emerged, and then underwater, once the cathedral has sunk back into the sea. It is a very beautiful piece.
