you'll definitely get some chops from this book, I forget the track #, but the song about a truck driver is very funky and a very cool groove to learn...
I don't know which albums you've been listening with his playing on it. But when i bought the book I was hoping to get some of the grooves he plays on BB King's Cd Perfectly Well. But they weren't there...
Nonetheless, you'll have several hours of fun...a very good insight into his style.
