Stuart Bull has an excellent teaching style and I do like the approach of utilizing Minor/Major triads first and then moving on to larger patterns. The DVD does not come with a booklet, which would have been nice. It would have been nice if it even had some .pdf files with patterns on them, but NO, none of this. So, while Bull's teaching style is great, you have nothing to work with once you turn the DVD off.
One of my pet peves with the whole sweep picking thing is the distortion. I would like to have heard some of the examples with less distortion or a completely clean tone. I tried searching for something like this on youtube, but had no luck. Seems like everyone who uses sweep picking has to have an assload of distortion behind it. Gets old. I like a bit of classic tone, a bit more "vocal".
End result... it's a good video and definitely a good purchase, but if you can get it used for say five to ten dollars go that route. Twenty dollars is too much for the amount of information you don't get.
