I feel like the Beatles 1962-1966 and 1967-1970 fits this well, for a couple of reasons. First, the Beatles grew in such a cohesive way, and the albums have such a clear divide on these two albums. You hear something happening at the end of the first one, but you put on the second and hear Strawberry Fields Forever and it's like a different band. Second, both albums have several important non-album singles. So there's a little added that you don't get just by listing to their albums.
