been recognised as having inspired new subgenres of music, anticipating electronica, punk rock, baroque rock and world music, among other styles. According to Rolling Stone, the album "signaled that in popular music, anything – any theme, any musical idea – could now be realized". Through the Beatles' example, psychedelia moved from its underground roots into the mainstream, thereby originating the longer-lasting psychedelic pop style. Russell Reising and Jim LeBlanc credit the songs on Revolver with "set[ting] the stage for an important subgenre of psychedelic music, that of the messianic pronouncement". As with Rubber Soul, Walter Everett views the album's "experimental timbres, rhythms, tonal structures, and poetic texts" as the inspiration for many of the bands that formed the progressive rock genre in the early 1970s. He also considers Revolver to be "an innovative example of electronic music" as much as it broke new ground in pop by being "fundamentally unlike any rock album that had preceded it". Rolling Stone attributes the development of the Los Angeles and San Francisco music scenes, including subsequent releases by the Beach Boys, Love and the Grateful Dead, to the influence of Revolver, particularly "She Said She Said". Steve Turner likens the Beatles' creative approach in 1966 to that of modern jazz musicians, and recognises their channelling of Indian and Western classical, Southern soul, and electronic musical styles into their work as unprecedented in popular music. He says that, through the band's efforts to faithfully translate their LSD-inspired vision into music, "Revolver opened the doors to psychedelic rock (or acid rock)", while the primitive means by which it was recorded (on four-track equipment) inspired the work that artists such as Pink Floyd, Genesis, Yes and the Electric Light Orchestra were able to achieve with advances in studio technology. Turner also highlights the pioneering sampling and tape manipulation employed on "Tomorrow Never Knows" as having "a profound effect on everyone from Jimi Hendrix to Jay-Z". Rodriguez praises Martin and Emerick's contribution to the album, saying that their talents were as essential to its success as the Beatles'. While also highlighting the importance of the production, David Howard writes that Revolver was a "genre-transforming album", on which Martin and the Beatles had "obliterated recording studio conventions". Combined with the similarly "visionary" work of American producer Phil Spector, Howard continues, through Revolver, the recording studio had become "its own instrument; record production had been elevated into art."
