Learn & Master Guitar, developed by experienced guitarist and instructor Steve Krenz, is one of the most comprehensive DVD-based video guitar lesson packages around.
It starts off with the absolute basics such as tuning and simple chords, but by the end of the course, gets into more advanced topics, such as soloing, improvisation, and chord substitution.
There are 20 DVDs in the package, each one covering in depth a specific topic listed in the accompanying instruction book, as well as 5 CDs with a great variety of decent jam tracks.
The quality of the material presented both on the DVDs and in the CD recordings is excellent, and one of the benefits of having the lessons on DVD, is that you can watch a particular lesson over and over again until you're happy with it...
