The Beatles(White Album) released in 68 is the " true masterpiece " of all their classic rock albums creatively, musically & artistically by the Beatles more so than their " highly overrated " psychedelic masterpiece Sgt. Pepper with rock, pop, blues, folk & a little avant garde while I have to admit I'm kind of " bias " to the Beatles late 60's period with their longer hair, outspoken attitude with more emphasis on rock more than pop but the White Album is the " essential classic rock album " which define the Beatles as a legendary rock & roll band with few equals.
