Cristian,

For what it is worth,

In the states there are still quite a few people who are "traditional musicians" by any definition, no matter how stringent.

They are living members of still living musical traditions who have learned in traditional ways. We refer to them as the "real thing."

Some but by no means all of them are ancient. They are probably people you've never heard of: Marvin Gaster, Sheila Kay Adams amd Bobby McMillan of North Carolina, John Morris, Dwight Diller, Dave Bing, Lester McCumbers, Frank George, and Phyllis Marks of WV, Paul David Smith and J. P. Fraley of Kentucky, etc.
