If you are asking the name of the musician and of the piece, doesn't seem the site gives any help for finding that.

If you want more information on the instrument, Wiki does give some good information. It even has a page listing many of the current musicians who use this instrument! It is very typical for Appalachian music of the 17th-19th centuries, much of which is likely to be of Scots-Irish origin, especially from the sound of this piece.
