On of strangest bits of folklore I ever found is a band called "Hav Ran" from Poland.

In southern Poland there is the mountain area of "Tatra" which produces a vivid and splendid folk music, using a language that is nearly, but not really polish. When I was in Gdansk I looked out for some polish folk music, but what I found was this unique mixture of Tatra folk and techno. Since the rednex' "Cotton eye joe" we know it works, since techno is dance music, like folk music too. But this polish band is far more inventive than that main stream compatible country/techno mixture.

I'm very sorry never to have found out more about "Hav Ran". Music from eastern europe doesn't seem to find the way west theese days. But there is a rich treasure to be dug out for western music lovers.
