I liked The Wall, but haven't listened to it in its entirety in years. I've heard several other concept/theme/story albums since and for what its worth, at least you don't need a five page program to figure out what the hell is going on. Lyrically, most of the songs stand alone and can be enjoyed by themselves. As an album, it has a great flow from beginning to end, which is a feat in and of itself given its a double album. Musically, it jumps from your stereo. So many epic concept albums are so ponderous (the bane of prog). This was Waters last great effort in my opinion. He never was this good again.
