Electric Purgatory kicked ass man.. great documentary. I even learned of a few bands I knew little about like 24-7 Spyz and Burnt Sugar.
There really was very little that I could argue with .. from the labels not knowing how to market black rockers to the black musician's influence on rock to the label of "sell out" given to black musicians that aren't doing R&B or hip hop by blacks as a general rule.
The history of the black musician and the influence the black musician has on rock and roll is thoroughly explored. Most folks know that the true roots of rock and roll are found in the Mississippi Delta from bluesmen like Robert Johnson. But, there were so many other black influences on rock music.
Very cool documentary and definitely one that I'd recommend all fans of rock check out.
