Warren Haynes - Electric Blues & Slide Guitar (DVD, 2005)

This instructional DVD does not follow the typical formula. It does not introduce any theory or technique nor does it rehash things you can find elsewhere. Warren Haynes takes a more creative right-brain approach to what makes improvising solos and slide work for him. Don't expect any rules or guidelines from him. The general theme is to keep an open mind and do what works for you. BUT here are a few things that work for him to get you to think outside the box.
As far as negatives, there are a few. If you have the VHS tape and wonder about what the bonuses are on the DVD, there are not many. The promised bonuses are little more than a biography, a discography, and you can select the scenes. The biography and discography are just text, no video or audio.
If you already have the VHS, the only real reasonto buy this is to have something a bit more permenant than VHS and the ability to quickly access portions of the DVD instead of tedious fast forwarding and rewinding. If you don't have the VHS and you are looking for something to give you a shot of inspiration and motivation, this is an awesome video.
