A. John Mayall & the Bluesbreakers was an English blues rock band, led by singer, songwriter, and multi-instrumentalist John Mayall, OBE. While never producing a radio-friendly hit on their own, the Bluesbreakers’ greatest legacy is as an incubator for British rock and blues musicians. Many of the best known bands to come out of Britain in the 1960s and 1970s had members that came through the Bluesbreakers at one time, forming the foundation of British blues music that still appears heavily in classic rock radio. Among those with a tenure in the Bluesbreakers are Eric Clapton and Jack Bruce (later of Cream), Peter Green, Mick Fleetwood, and John McVie (who would form Fleetwood Mac), Mick Taylor (the Rolling Stones), Aynsley Dunbar (Frank Zappa and The Mothers of Invention), and numerous other musicians.
Formed in March 1963 The Bluesbreakers became an ever-evolving lineup of more than 100 different combinations of musicians performing under that name. Eric Clapton joined in April 1965, just a few months after the release of their first album. Clapton brought guitar-led blues influences to the forefront of the group; he had left The Yardbirds in order to concentrate on the blues.
