i gotta agree with rockadanny--sgt. pepper was certainly eagerly awaited and massively hyped, but aside from more lavish production didn't really do anything musically that different from rubber soul or revolver (or for that matter, from pet sounds or some of the other ambitious pop of the era like the left banke or the zombies). i was also kinda underwhelmed by sgt. pepper--other than day in the life, the songs just don't move me like virtually the rest of their catalogue. just my biased and likely misguided opinion, of course.
to the original question, in addition to many of the above-named records, it seems like virtually everyone who heard "velvet underground and nico" was inspired to form a band to remake it.
