Happy Traum's name came up. He has an extensive list of VHS video's and, now, DVD's that teach fingerpicking for guitar. He can be found at homespuntapes.com. Stefan Grossman's tapes and videos can be found at guitarvideos.com. Stefan also has numerous videos of many now deceased blues artists. He also has some still living players on video in concert.

Good luck with all of this information!
