I know that if I say that this is the Stones' Sgt. Pepper's I'll get tons of hate, but just hear me out: Between the Buttons is The Rolling Stones going psychedelic in a big way and succeeding, much like the Beatles did with Sgt. Pepper's. Granted, there's a lot of sonic differences between the two, as each band still definitely sounds like themselves (and the Stones don't go as full psychedelia as the Fab Four), but conceptually they're quite similar in what they wanted to accomplish musically. The Beatles still did it better, but it's a lot closer than you might think. It's a very obvious stab at the genre, but it also works very well for what it is. To me, this is the Stones' best album up to this point in their catalog.
