I saw an interview of David Gilmour where he said DSOTM was a concept album. I guess that's like Sgt. Pepper, or Tommy, where every track shares a common theme and their all linked together somehow. I'm trying to figure out what the whole album is saying. My take on it is that there is natural harmony to the universe, but behind this is overshadowed by a dark chaos. I got that from "And everything under the sun is in tune, but the sun is eclipsed by the moon". WHat du u peoplz think?
