This book is absolutely the best 2nd book for a beginner. (The best 1st book is Wanders' Go for .. Guitar - Basic.) It has the most gradual progression into playing 2-part classical guitar from music notation that I've ever come across. Its many pieces are very simple yet pleasant to listen to. My student is very reluctant to try anything new - but because Wanders introduces each new skill so simply, she has happily worked her way through this book.
I have to admit, this is quite an interesting collection.
It is extremely versatile in that it expresses every genre and its contained flavors, while completely guitaristic and simple to play.
