Well, the first one started quite an interesting thread, and I can only hope this next choice will have the same results. I'm sure it will please Resident Loser since it's none other than The Beatle's - Sgt. Pepper's Lonely Hearts Club Band (1967).

There are those who rate Revolver or the White Album higher (I do), but Sgt. Pepper's made the watertight case for pop music as an art form itself; until then, it was thought the silly, transient stuff of teenagers. At a time when all pop music wsa stringently manufactured, theise McCartney-driven melodies and George Martin-produced whorls of sound proved that untried ground was not only the most fertile stuff, but also the most viable commercially. It defined the Sixties and gave white rock all its airs and graces. Without this pop would be a very different beast.
