Benny Greb: The Language of Drumming Question

Hi guys... I've very very interested in picking up this 2 DVD instructional set. I am wondering if anyone has the book of the same title and if it's worth the extra purchase. I've heard the one DVD has a huge PDF on it, but I'm not sure if it's the same thing as the book.



Can anyone confirm either way?
