I've purchased loads of books and DVD's over the years. This book is simple and consise and for anyone that wants to 'dip their toe' into the blues I would highly recommend it. I'd recommend copying out the scales yourself as they're a bit small for the kindle. Finally the price is just rediculous, great value.
A great little book. It explains in a simple, direct way, the basics of blues scales, chords and song structures. I am an intermediate level acoustic guitar player with ambitions to play acoustic blues and this is just right for me.
