The Jeff Beck Group was a rock band formed in the U.K. in February 1967 by ex-Yardbirds guitarist Jeff Beck. Their innovative approach to heavy-sounding blues was a major influence on popular music in the late 1960s and early 1970s. The first Jeff Beck Group was formed in the U.K. in 1967, consisting of Jeff Beck guitar, Rod Stewart vocals, Ron Wood bass, and Aynsley Dunbar drums. Beck had signed a personal management contract with famed U.K. singles record producer and manager, Mickie Most.
