Davies was an innovative harmonica player who exerted a huge influence on his contemporaries. He was an original member of Alexis Korner's Blues Incorporated in 1961 but left in late '62 to put the Allstars together with the aim of playing Chicago-style blues. The Allstars quickly became a popular attraction in the clubs of London and, occasional members included pianist Nicky Hopkins, guitarist Jeff Beck and drummer Micky Waller, who all went on to make names for themselves later in the decade.
