Composer and journalist Frank Oteri recognized "Pet Sounds" as a "clear precedent" to the birth of album-oriented rock and progressive rock. Bill Martin, an author of books about prog-rock, felt that the album represented a turning point for prog as the Beach Boys and the Beatles transformed rock music from dance music into music that was made for listening to, bringing "expansions in harmony, instrumentation (and therefore timbre), duration, rhythm, and the use of recording technology". Asked in a 1968 interview about the Beatles' role in rock's "progress toward an art form", Led Zeppelin founder Jimmy Page responded, "I think the Beach Boys tried to do it first. I think there were lots of Beach Boy things on the "Revolver" album. Especially, the vocal harmony. Wilson really said a lot in his "Pet Sounds" album." Gang of Four's Andy Gill argued that "so many rock bands took ["Pet Sounds"] as a green light to get clever—to start playing with the time signatures, to go prog. You know, 'Let's put a french horn in there!' Before you know it, you've got Queen."
