"This book is very very well written, it is easy to follow and will most certainly improve your playing. His method combines two traditional styles of learning into a more modern effective way of learning. While this book will help you get better at guitar it will also help you to understand what you are playing, and how everything relates to each other in a way that will improve your fluidity on the guitar, and any other instrument for that matter." - Amazon Review
