Found a documentary on fiddling picked up and transformed by indigenous peoples in Northern USA & Canada. I've just purchased the rather pricey dvd from the film maker's site... so I'll see if it's worth it.
Turns out the film maker, Michael Loukinen, is a Native Michigander of Upper Peninsula Finnish descent - Professor of Sociology at Northern Michigan University, who turned down a 30 year road of documentary film making - mostly History & Culture of the Michigan U.P.
A vibrant and perceptive documentary that celebrates the fiddling dancing traditions of Native American and Metis families on both sides of the United States and Canadian border. Although European in origin, fiddling and step-dancing traditions of both Indian and mixed-blood descendants reflect a strong Native American influence and are sustained largely by Native American spiritual ideals. This remarkable film weaves music, dance, and storytelling into a compelling and entertaining experience.
