2/5 Really not helpful at all
  by Lance Manion (boston)
This DVD is next to worthless for me. no explanation of anything, particularly in the crucial rhythm section. Just some show-offy guitar playing by the guy in the video, with zero explanation or context or insight in any of the material.

Awful.

5/5 Increases your Chord 'Vocabulary' & Fretboard Knowledge
  by Elizabeth Kay Heinecamp (Milwaukee, WI)
I actually bought the book to this video first as a music student, but by FAR the video is MUCH BETTER. It's ideal for an advanced beginner or intermediate player who 1) already knows 1st Position playing thoroughly and the major chords/chord shapes of C, A, G, E and D, and 2)understands basic theory like 'I-IV-V' chord progressions, etc., and 3)know the scale with each chord shape.

If you've always admired rhythm guitarists and their ability to play all over the fretboard with ease (not to mention artistically) you need to buy this video. In a very logical, simple and step-by-step process, you will learn how to build up your chord knowledge so that you can play chord changes SMOOTHLY, anywhere on the neck. No more bouncing around from 8th fret to 1st fret 'cuz you don't know any other voicings besides the basic barre shape.

One of my favorite aspects of this video are the sample tunes, in different styles. He shows you quite a few little embelishments and tricks which add nicely to background playing. These help you sound more professional, and less like your standard garage band player.

Overall an excellent investment of your money and time - if you practice and follow the instructor faithfully, you will increase your chord vocabulary hugely and not rely on simple barre chords all the time.
