Passage: The band's earliest influences include Elvis Presley, Carl Perkins, Little Richard and Chuck Berry. During the Beatles' co-residency with Little Richard at the Star-Club in Hamburg, from April to May 1962, he advised them on the proper technique for performing his songs. Of Presley, Lennon said, "Nothing really affected me until I heard Elvis. If there hadn't been Elvis, there would not have been the Beatles."Other early influences include Buddy Holly, Eddie Cochran, Roy Orbison and the Everly Brothers. The Beatles continued to absorb influences long after their initial success, often finding new musical and lyrical avenues by listening to their contemporaries, including Bob Dylan, the Who, Frank Zappa, the Lovin' Spoonful, the Byrds and the Beach Boys, whose 1966 album Pet Sounds amazed and inspired McCartney. Referring to the Beach Boys' creative leader, Martin later stated: "No one made a greater impact on the Beatles than Brian [Wilson]." Ravi Shankar, with whom Harrison studied for six weeks in India in late 1966, had a significant effect on his musical development during the band's later years.
