Muddy Waters
As a recording artist the 1960s were not good. But the white audience even in Europe discovered him. A band from London was named after one of his songs. (The Rolling Stones). His importance for young musicans was documented in the album "Fathers and Sons" where Muddy Waters, the father, played together with his sons Mike Bloomfield, Paul Butterfield and Donald "Duck" Dunn, all of them white. In the 1970s he tightend his reputation as live act. He played great festivals like the Montreux Jazz Festival. But also his albums were acclaimed, so the album "Hard again". This album was produced by the guitarist Johnny Winter.
