Of course the grandaddy of them all is Clarence White who was in the Kentucky Colonels and the Byrds. Unfortunately not much of his stuff has been re-released on CD. For those unfamiliar with those names I listed on my original post,for a good place to start I'd recommend the following as they're pretty easy to find.

Tony Rice - 58957: The Bluegrass Guitar collection - released in 2003. All instrumental. Also 'Backwaters' which is his jazz-bluegrass fusion.

Dan Crary - 'Guitar' and 'Lady's Fancy'.

Russ Barenberg (with Jerry Douglas) Skip Hop and Wobble

Wyatt Rice -'New Market Gap' .Tony's younger brother.

David Grier - 'Freewheeling'. 'Ive got the house to myself'.

These guys can not only play fast but also real clean.
