content: This album certainly expanded the boundaries of what pop music could be, but in doing so strays a little far from the roots of rock for my tastes. I find the almost complete absence of George Martin's name from other reviews to be vexing. Lennon, McCartney and Harrison all do their part, to be sure, but I don't think George Martin gets enough credit (not just for this album but for The Beatles, period). In short, it's a must-have, but on the whole, give me Revolver.
