One of the great places to start your listening is to get the cd called "Old time music from Clarence Tom Ashley's " . put out by Folkways now Smithsonian ( I think ). There are so many great players. . If you had any chance to see Pete Peterson and his gang even at the other side of Briton it would be worth the trip . Ray Allden ( one of the greatest frettless banjo players of our time ) and David Howard have a band that I want to introduce to Banjo Ray so they may get to Yorkshire sometime . Ray is a pritty great frailer at that so you have him and his get togthers to listen in on as well .
          Also can you rent the movie Songcatcher ? There is nothing so powerful as a good Old Time fiddle and there is one in that movie . Sliding a note up to match another plantive note and finding chordal archutecture around the tune can be like nothing else . Its sounds simple but there is lots going on . Ahh Good luck in your search .If I ever get back to Yorkshire I'll put something here at Mudcat and I play some old Time banjo as well .   All the best , Guy
