Query: Buy only if you are a jazz guitarist.

The tiltle threw me off since i did not know who Danny Gatton was.I was expecting to learn some amazing rhythm patterns and great strummings techniques because of all the other reviews that I have read ,but all I saw was the same pluck and pick patterns and different jazz chords (some blues chords as well).I guess You have to be a fan of Mr.Gatton to enjoy the material.I know I did not enjoy it at all or really learned anything(I could not bare to sit through the whole thing but I forced myself).The only part I enjoyed was about one minute worth, when Mr.Gatton had the acoustic guitar(he used an electric guitar throughout the dvd)and used a really cool rhythm.
