I finished this book feeling somewhat in awe of a very sincere and hard working man. As far as an autobiography is concerned it is extremely light on detail after about 1970. However the stories of his early years growing up on cotton plantations and his first twenty years in the music business are rivetting. His musical interests are more catholic than you might expect and he is almost the only musician I've ever read about who didn't mess up with drugs. As often with these kind of books the musical detail is fascinating and he got me listening to Count Basie and Bukka White to name but two.
There are also some heartbreaking and interesting stories about racism. Mr King has a firm commitment to a turn the other cheek approach and is a good spokesman for it.
