I liked this video, as David is a really good teacher and presents his concepts very well. His approach to getting a good sound is very important, and the scale patterns he shows you work in a lot of situations. This video will introduce you to the world of playing electric guitar in the open G and open E tunings. David begins with the basic of getting a good slide sound, takes you through slide scale patterns and riffs in open position and up the neck; demonstrates step-by-step how to create riffs, solos; backup parts in the style of Muddy Waters, Elmore James, Duane Allman and Ry Cooder. The accompanying booklet comes complete with diagrams and notations which correspond to this video.
