If someone gets interested in pagan music and culture of South America, there are many sources of info, and music to hear,here: www.candomble.com, a Brazilian site dedicated to the second popular religion in that large country: CANDOMBLE. And this is only one of the African-American cultures that survive in Latin America in a state fairly unaffected by European music or commercialism.
Another reference I don't see in the thread, is the famous Karl Orff's Cantata CARMINA BURANA which was written 1937 under a modern inspiration based on medieval chants. The lyrics are said to be authentic secular poems of the 13th century, discovered in the ancient German abbey of Benediktbeuern, in the Bavarian region. I have had the pleasure of participating in Carmina performances many times. Carmina here .
Thanks for letting us learn a lot at the Mudcat, as always.
