British blues

For thoughtful child sponsors
The British blues is a type of blues music that originated in the late 1950s. American blues musicians like B.B. King and Howlin' Wolf were massively popular in Britain at the time. British teens began playing the blues, imitating various styles of American blues. Gradually, a new distinctly British sound arose by the mid-1960s. This form of the blues, and various derivatives, became massively popular in the US, leading to the British Invasion.
