Well I'm happy to pre-judge the series, it could be even more evidence of White men getting fat on Black mens talent. Robert Johnson didn't sell his soul to the Devil, he sold it to the American Record Company who were bought up by Columbia Records who were bought up by Sony, and they get most of the money. In my experience music documentaries major on boring and intrusive voice-overs and precious little of the actual music they purport to promote. I look forward to being proved wrong.
