The Yardbirds, who produced three of Britain's most influential rock guitarists, followed in the footsteps of the Rolling Stones (Rolling Stones, the) on the western London rhythm-and-blues circuit in 1963–64, their early repertoire consisting almost exclusively of cover versions of songs by artists who recorded for the Chess and Vee Jay record labels. With Clapton (Clapton, Eric) as lead guitarist, the band created the “rave-up,” accelerating their playing until it transformed into white noise. Employing distortion and reverb (a succession of echoes that blend into one another to create sonic space), Clapton's successor, Beck, pushed later hits like “Shapes of Things” (1966) into the realm of psychedelic rock. Page, later the leader of one of the most successful heavy metal–hard rock groups of the 1970s, Led Zeppelin, initially joined the Yardbirds as a replacement for bassist Samwell-Smith. Switching to guitar, Page joined Beck as the band's colead guitarist—though the two played together on only one single, the visionary “Happenings Ten Years Time Ago” (1966), before the band's short-lived final lineup dissolved in 1968.
