John Mayall (born November 29, 1933) is a pioneering English blues singer, songwriter, guitarist, keyboard player and harmonica player.

John Mayall's most well-know band is called John Mayall & The Bluesbreakers. They started out in the late 1950s in England, using American style blues as a starting basis for their sound, which has evolved from album to album. And while at one point John Mayall was playing a fairly jazzy sound, he has eventually come back to the blues.

One of the interesting features of the Bluesbreakers is that members changed on a very regular basis, and many have gone on to well deserved fame and fortune with other bands and as solo acts. Past members include: Eric Clapton, Jack Bruce,. Peter Green, John McVie, Mick Fleetwood, and Mick Taylor.

John Mayall stands out for several reasons - his standing up for the blues, while experimenting with different approaches, his ability to attract the best of musicians; and perhaps most notably his willingness to work with musicians who far outshine him in sheer ability.
