British rhythm and blues (or R&B) was a musical movement that developed in the United Kingdom between the late 1950s and the early 1960s, and reached a peak in the mid-1960s. It overlapped with, but was distinct from, the broader British beat and more purist British blues scenes, attempting to emulate the music of American blues and rock and roll pioneers, such as Muddy Waters and Howlin' Wolf, Chuck Berry and Bo Diddley. It often placed greater emphasis on guitars and was often played with greater energy.
The origins of the movement were in the British jazz, skiffle and folk movements of the 1950s. The 1958 visit of Muddy Waters influenced key figures Cyril Davies and Alexis Korner to turn to electric blues and form the band Blues Incorporated, which became something of a clearing house for British rhythm and blues musicians. A flourishing scene of clubs and groups emerged in the later 1950s and 1960s and bands began to break through into mainstream success. Major acts included the Rolling Stones, Manfred Mann, the Animals, the Yardbirds, Them, and the Spencer Davis Group, who dominated the UK and US charts from 1964, in the wake of the Merseybeat craze, becoming central to the beatnik and mod subculture in the UK and a second wave of British Invasion acts in the US.
