And there are lots of ethnic groups that have their own music. They seldom show up at our "folk" festivals even though you can't deny that they're "folk" and they might live right next to us. I'm thinking of German polka bands, Swedish fiddlers and nyckelharpa players, Hmong qeej players, mariachi bands, etc. I have never heard Somali music, although Minnesota (where I live) has thousands of recent Somali immigrants.

When we think of "folk" we mainly think of the traditional music of English-speaking countries. If we're unusually broad-minded, we might consider other Europeans.

I guess I'm agitating for people who organize "folk" festivals to be a bit more broad-minded than they already are.
