This was a good book about the history of blues music and not just about the chess label. There is a lot of information about the people sing blues music before Muddy Waters really made popular. Also there is a lot of information about how the label came to be. The other parts of the story are good, it is just some of the stuff from other labels. How the record company cheated them out of money maybe it happen, matbe not. Not every singer said the same thing. But I am sure some of that had to be going on there if it was going on at other places in the 50's. A good book about the lifes of some of the biggest blues singers and musicans that was really good reading about. Overall a good book.
