Hi,
I've had the book for quite a while but only recently got the DVD. I'd say the DVD is very useful on it's own without the book.
The book deals with a lot of fundamentals, like open string exercises, rhythm exercises, etc that would be fairly repetitive in an instructional DVD. The DVD deals primarily with concepts, line construction (also in the book) and group playing. The DVD is very much like a personal lesson in delivery.
There's also PDF files for each tune that isplayed - bass line and melody.
Definitely worth getting IMO. (The updated book has some great stuff too, so worth checking out also).
