By the age of 12, Frampton played in a band called The Little Ravens. Both he and David Bowie, who is three years older, were pupils at Bromley Technical School. The Little Ravens played on the same bill at school as Bowie's band, George and the Dragons. Peter and David would spend time together at lunch breaks, playing Buddy Holly songs.
He became a successful child singer, and in 1966 he became a member of The Herd. He was the lead guitarist and singer, scoring several British pop hits. Frampton was named "The Face of 1968" by teen magazine Rave.
While playing with Humble Pie, Frampton also did session recording with other artists, including: Harry Nilsson, Jim Price, Jerry Lee Lewis, as well as on George Harrison's solo All Things Must Pass, in 1970, and John Entwistle's Whistle Rymes, in 1972. During the Harrison session he was introduced to the "talk box" that was to become one of his trademark guitar effects.
