Oscar-winning actor and avid blues fan, Morgan Freeman, hosts a fascinating program exploring how the blues has developed and diversified from the 1960s onwards, and in the process played a huge role in shaping the face of rock music. He begins with the British Blues boom of that decade which saw many white musicians pick up the blues baton: musicians such as Led Zeppelin, the Rolling Stones, Fleetwood Mac, and Eric Clapton. Clapton features in live footage recorded at the world-famous Montreux Jazz Festival. Clapton’s contemporaries in the 1960s included Jimi Hendrix and Carlos Santana. We see Santana jamming with the Saharan band Tinariwen whose hypnotic sound takes us back to the very roots of the music in Africa. This film also celebrates more recent blues contributors including Robert Cray and Sweet Honey in the Rock. Freeman showcases the sounds of Jon Spencer's Blues Explosion, who in turn influenced The White Stripes; and the hip-hop/blues combination delivered by actor-musician Chris Thomas King. King, Speech from Arrested Development, G. Love, and Buddy Guy provide lively analysis and insight.
