I think the reason they don't really celebrate an album from cover to cover too much is because it is just boring. For me, part of the excitement of a concert is trying to figure out what they will play next and hoping they will play my favorites. I'm always listening ot the first notes of the next song trying to figure it out. If I know what is coming next, it takes all the spontaneity out and alot of the excitement. If they played Nimrod cover to cover I would take a piss break at Platypus. PLus, if I wanted to hear Nmrod cover to cover I would just put the album on. Also, just because an album flows well, doesn't mean it will flow well in a concert setting. I want excitement, to be entertained. For me, playing an album cover to cover kind of takes that excitement away.
