This is Kenny's second book on acoustic blues. I haven't yet seen the first, apparently intended for raw beginners. This book could be used by a raw beginner with a considerable amount of determination; I recommend it for someone who has been playing long enough to know some chords and not be completely lost by basic theory like I-IV-V progressions.
This is the book that finally lifted me out of endless, aimless noodling and set me on track to real accomplishment with the guitar. Kenny starts out with some very simple stuff, and then each lesson builds on what you've already learned. Before long, you're playing things that sound REALLY COOL--a sure way to keep you working and draw you further in. And I'm not just talking about simple shuffles either--by the time you get to the end of the book (it took me about six months) you're playing some really fun, and sophisticated-sounding, music. Excerpts and riffs from Blind Blake, Big Bill Broonzy, and Rev. Gary Davis, among others. The book ends with an introduction to slide.
The book includes a CD with the music played slow, and then up-tempo, along with some coaching from Kenny. Extremely helpful in learning rhythms.
I've spent a lot of money on a lot of books. This one ranks in the top two or three I've ever bought. I can't speak highly enough of it.
