Something of a cliche for such a list anymore, but this album from 1967 arguably started the concept album (without really being one). From full orchestras to traditional Indian music, the more experimental than ever Beatles assembled an album as strange, beautiful, and diverse as the famous collage adorning the album cover that simply must be listened to from beginning to end.
As great as many of the individual tracks are, the album doesn't really hang together until you wedge Penny Lane and Strawberry Fields back in there -- preferably between sides A and B, to keep the flow. That also gives the album a kick in the pants at just the right juncture to carry you through the second half.
