This subject deserves its own thread, Kerberoxu. There are many living musical traditions, most of which I know nearly nothing about. I appreciate very much when somebody takes the trouble to put together some background and a few links.   

Nowadays, it's possible to fine nearly any kind of music online, the trick being that you have to know about it first. it's a cold and rainy night here, and I am googling Nicomedes Santa Cruz...ah, here's "No Me Cumben"-it's getting warmer already!
