Passage: Rubber Soul had marked a major step forward; Revolver, released in August 1966 a week before the Beatles' final tour, marked another. Pitchfork's Scott Plagenhoef identifies it as "the sound of a band growing into supreme confidence" and "redefining what was expected from popular music". Revolver featured sophisticated songwriting, studio experimentation, and a greatly expanded repertoire of musical styles, ranging from innovative classical string arrangements to psychedelic rock. Abandoning the customary group photograph, its cover – designed by Klaus Voormann, a friend of the band since their Hamburg days – "was a stark, arty, black-and-white collage that caricatured the Beatles in a pen-and-ink style beholden to Aubrey Beardsley", in Gould's description. The album was preceded by the single "Paperback Writer", backed by "Rain". Short promotional films were made for both songs; described by cultural historian Saul Austerlitz as "among the first true music videos", they aired on The Ed Sullivan Show and Top of the Pops in June 1966.
