So here it is, my (for now) definitive Folk Funk Top Forty ~ Part 1
But what is this folk-funk thing anyway? I'm not sure if I can put a finger on it, not in precise words anyway. To me, the groove sounds like it has one leg shorter than the other, like a funky limp. Oh, and a flute is always a nice addition. Feel The Spirit by Heaven & Earth is a great place to start. Does that help?
