Good For Beginners
This video features Keith Wyatt who is an accomplished guitarist and excellent instructor. Keith appears in many guitar instruction videos.

He starts off introducing the I-IV-V blues progression and teaches the progression in the key of E using open position 7 chords. He also shows the student how to spice up the progression using embellishments and base notes. The second section Keith teaches the blues shuffle in the key of E and again shows the student how to spice up the progression with embellishments and base notes. He also demonstrates some very basic turnarounds. At the end he introduces the use of a capo but doesn't go into much detail.

He leaves the student not only with the ability to play some pretty cool sounding blues progressions but with some tools and advice that the student can use to play around and develop additional embellishments.

All of the material is very, very simple and straightforward. It does not cover soloing or anything very technical. A beginning guitar student could get a lot out of this. An intermediate student who has no experience with acoustic style blues guitar can also learn a few tricks and have some fun going through the material.

Ultimate Beginner: Beyond Basics - Acoustic Blues Guitar
The tape started off very good.
I learned some basic structure of 12 bar blues and some alternate fingering for blues chords.
However, just as I was getting the rythm down, the instructor started to introduce some filler notes between chords and that's when the instructor went much too fast for me to catch on.
Beginning starts basic and then goes into hyperspace as if the insrtuctor is running out of time.

Perfect
Great for blues beginners.
Keith is a very good teacher.
I recommed the tape to anyone who plays guitar (basics) and wants to enter the blues world.
