The best Beatles album? The rock historians often point to Sgt Pepper’s Lonely Hearts Club Band as the moment, in 1967, when rock magically grew up and became a legitimate art form, at least as it was perceived by the mainstream media. Many fans love the sprawl and variety of the self-titled 1968 double album, popularly known as The White Album. In some quarters there’s a fondness for Abbey Road and its side-long suite of mini-songs, and lovers of the Bob Dylan-influenced folk-rock of the mid-‘60s cherish Rubber Soul above all. They all have merit, but none of them is as consistently brilliant and innovative as Revolver.
