Clyde Davenport, from Wayne County, Kentucky, is one of the last old-time fiddler still alives today (born in 1921, he's 87 years old). He plays also the banjo, mostly clawhammer style, as you can hear on this lp issued by County Records. There's also an old recording of Burnett & Rutheford included in the album because Leonard Rutheford was Clyde's main influence on the fiddle.
