folk and capital are pretty much oxymoronic.

To be the capital, you need organization. You get enough organization, you need professional organizers. Once you get professionals, out goes the folk.

Epicenter may be a better term, but it's silly because there are dozens of different folk styles that sould not be lumped together. Take celtic folk, for example - how do you mash all that is Irish, Scottish, Welsh, Mannish, Breton, Galatian, as well as neo-Celtic such as Australian, American, Canadian, British together? Where exactly in the spot that embraces all of that?
