At least, the day has already come for all races joining together to LISTEN to music of every source, and that´s good. And even some adventurers like Escamillo who being descendant of Frenches and Spanish dare to stand in front of a piano (with somebody else playing) and shamelessly sing gospel and blues.(And soon traditionals)
As to Ed's question, I think that the Mudcat does nothing except reflecting the reality of people's tastes and cultural roots, and that´s good too, as far as doors are open for everybody, which I can testify, as the only Latin American here, and as far as everybody respects the general orientation and don´t try to deviate it. In Argentina, the tango is a typical urban expression, played and composed by Italians and Spanish and even Arabs descendants, while country music is pretty different and mostly originated in provinces, both genres affected by African rhytms too.
Hope to have contributed to a good and friendly confusion. Un abrazo - Andrés
