I bought this DVD to try to extend my competence (good Rock and Roll rhythm player) into Rockabilly guitar playing and I was expecting a course to help me progress. This isn't that. It's just an expert demonstrating various quite complex rockabilly techniques used by well-known rockabilly artists. There is an instruction booklet showing both music and tab to accompany the DVD.
However, I found the DVD more demonstration than lesson. In my opinion, you need to be a very competent guitarist to benefit from this DVD. You need to know your chords and their various 'voicings' and be able to play them
The DVD is also quite dated having been made in 1999 and the vidoe quality is only average.
Having said that, for those guitarists who are already very good/excellent and want to the explore rockabilly style, this DVD may be all they need to develop it.
