Alexis Andrew Nicholas Koerner (19 April 1928 – 1 January 1984), known professionally as Alexis Korner, was a British blues musician and radio broadcaster, who has sometimes been referred to as "a founding father of British blues".[2] A major influence on the sound of the British music scene in the 1960s,[3] Korner was instrumental in the formation of several notable British bands including The Rolling Stones and Free.
In 1961, Korner and Davies formed Blues Incorporated,[10] initially a loose-knit group of musicians with a shared love of electric blues and R&B music.[4] The group included, at various times, Charlie Watts, Jack Bruce, Ginger Baker, Long John Baldry, Graham Bond, Danny Thompson and Dick Heckstall-Smith.[4] It also attracted a wider crowd of mostly younger fans, some of whom occasionally performed with the group, including Mick Jagger, Keith Richards, Brian Jones, Geoff Bradford, Rod Stewart, John Mayall and Jimmy Page.[11]
