This book takes all the random tidbits of theory, chord names, and scale names and puts it together in a laser pointed format that hits you in the head like a Les Paul and... BONK, you understand!
If you know how to read... any style, and any skill level will benefit from this book.
The best part about the book is the diagrams displaying how the chord and scale forms tie together. The book tells you and shows you.
I have bought several other books on technique and theory and believe that I will be refrencing this book long after the others are collecting dust on a shelf.
