The Advancing Guitarist by Mick Goodrick
Mick Goodrick is Berklee School of Music’s guitar guru to the gurus, I think it’s fair to say. If you’re SERIOUS about your guitar playing, you listen to whatever Mick says. I’ve had this book for 20 years, and I still
learn something new everything I open it. As long as you’re at least an intermediate player and are serious, you’ll get alot out of this book -revolutionary.
