If you’re a fan of the film Genghis Blues (which you should be; it’s a swell film), then you might very well like this performance of “Crazy Horse” by Mathias Duplessy and the Violins of the World.
That weird instrument on the left is evidently the Nyckelharpa, or key fiddle.
Unfortunately, the album this is from doesn’t appear to be available in the U.S. yet…
