My statement was relative. The Wall is not as interesting from a musical point of view as is WIsh You Were HEre or Dark Side. Hell, Dark Side has one of the most interesting modern songs, "Money" with two different time signatures. THe bass is playing 7:4 time while the sax and guitar is playing 4:4. The song also alternates time signatures. This is far more interesting than "Another Brink in the Wall."
Don't get me wrong, The Wall has some great musical moments. Comfortably Numb which was written by Gilmour, if very interesting as "Is there anybody out there?"
