Primal Twang: The Legacy of the Guitar is a DVD of performances from September 2006 in San Diego featuring some great guitarists. From the Primal Twang Web site:

The story of the “instrument of the gods” was told through a combination of onstage narration, video projections of rare historical footage and electrifying live performances by world music legend, Dan Crary and an all-star ensemble of international guitar greats, including Grammy-winners Eric Johnson, Albert Lee, Andrew York, Mason Williams and Doc Watson. Together, in person, for the first time on any stage!

This looks like a great DVD for guitar lovers! You can purchase the DVD on the Primal Twang Web site. Check out a preview below:
