by Claude Debussy is one of my favorite pieces of music.
This electronic version performed by Isao Tomita on Snowflakes Are Dancing (1974) was used in the first planetarium show I ever did. The show was a live lecture for some 50 minutes (too long, but these were the old days of longer attention spans) and the show (created by Mike Hood) ended in a beautiful sun rise with this music. We only used the piece up to the 3m35s mark or so, fading it out there.
