Phew! I forgot about youtube. My Rog was explaining that two llaneros will do what they call "contrapunteo" a back and forth improv of rhyming verses accompanied by harp and small guitar or uke.He calls it their kind of "rap." There's a really good example HERE on youtube. What fun. It's just like the tapes he brought home. It's great to actually see them. Those harps are something.
