I was browsing in Guitar Center when I came across this book. I will admit I'm not a fan of Billy Sheehan's music... it smacks a bit too much of that 80's pop-metal kitsch. However, that has nothing to do with my review here: I respect his talent and was curious to see what kind of riffs he used.
This is absolutely not an instructional book/DVD for an advanced bass player. There are zero exercises in this book. Instead, the book/dvd combo is filled primarily with the following sections: amp and equipment, strap length, stage presence, bending the neck, and a few brief discussions of actual technique (natural harmonics, pitch harmonics, and two hand tapping). I'm not even joking, this is literally mis-labelled as being an "advanced book". If you have been playing bass for more than a month, you probably already know everything in this book... there is almost nothing useful here that you couldn't garner from reading forum postings on the web.
The music exercises (on the aforementioned areas: natural harmonics, pinch harmonics, two hand tapping) have a single measure exercise on a single page and the DVD doesn't even go that far. The DVD basically amounts to an interview with Billy and the book just reiterates the same points with a slight increase in content.
The bottom line: this is not a worthwhile purchase unless you are an absolute beginner (then you can learn more from reading a whole page on strap length and four pages on amps). Do not be misled by the "advanced" title. This is strictly a book for the rookie. I regret this purchase and am very disappointed.
An aside: neck bending is not really that useful, don't do it unless you play a Fender style bass and you can afford to replace the neck in a few years.
