 Author Shawn Levy writes that the album presented an alternative reality that contemporary listeners felt compelled to explore further; he describes it as "the first true drug album, not a pop record with some druggy insinuations, but an honest-to-heaven, steeped-in-the-out-there trip from the here and now into who knew where".According to Simon Philo, "Revolver" announced the arrival of the "underground London" sound, supplanting that of Swinging London.Barry Miles describes the album as an "advertisement for the underground", and recalls that it resounded on the level of experimental jazz among members of the movement, including those who soon founded the UFO Club.
