For anyone interested in a learning more about the blues, including it's history, different styles and most important musicians, this book is an excellent choice. It traces the music from it's roots in work songs, gospel and tent shows through the country blues of the South and the electric blues of Chicago on to the modern era.
The writer clearly has great admiration for this music, not only for it's creative spirit but as a reflection of the black experience in America and the struggle of so many folks to survive bigotry and economic injustice.
Top notch blues perfomers like Bessie Smith, Robert Johnson and Muddy Waters are covered as well as lesser known but still influential talents such as Gus Cannon and Henry Thomas. Written in 1976, Oakley's comments on the contemporary blues scene can sometimes sound dated. But an excellent afterword, written in the late 90's, bring it somewhat more up to date. If you want to know more about the blues then this book is a great place to start.
