Here are a few sound samples
Here's Uncle Dave with Railroading And Gambling, real audio courtesy of CD Universe. (available through the Mudcat links)
And here's Art with In And Around Nashville from the Waterbug.com site (wave file)
One more, Sara Grey, Down The Road, also from Waterbug. There are many fine women players, too!
I know, this does not necessarily contribute to Banjoman's request much, but these are among my favorite recordings.
