Okay Marty D, for starters go to Folklore Productions. Drill through the menus (artist info) and you'll find bio, tour info and dates, and more on Doc Watson.

As for recordings, there are so many I don't know where to start. You could go to MP3.COM and do a complete discography search.

Certainly if you do not have it, you must get WILL THE CIRCLE BE UNBROKEN which was released by The Nitty Gritty Dirt Band, but it is a cornucopia of blue grass legends performing together, some of whom include: Doc, Mother Maybelle Carter, Earle Scruggs, Merle Travis, Jimmy Martin, and many others. This is a must have double album. I don't think many would disagree with me.

And if you can find it (been out of print for a while) a CD with Chet Atkins and Doc Watson made in 1979, called simply "Chet & Doc". Phenominal playing, all duets with only bass, and light percussion accompaniment. Killer!

Hope this at least starts you in the right direction. Best of luck.
