Along with "The Advancing Guitarist" by Mick Goodrick, this book is intended to push your musical boundaries. The emphasis is on orchestrated music, but I have found application in all the music I do and love. Sherman approaches music theory in an exciting, creative, and stimulating manner.

If you feel that your art is stagnating, buy this book. It will make you explore facets of music you never considered seeking out, and I guarantee a fascinating journey.
