I read an interesting article on cubanow.net interviewing Enid Rosales, one of the new wave of tres players in Cuba.
She talks about using the Cuban tres in areas beyond traditional Cuban son and popular music.
I just ran across a very interesting presentation on Tumba Francesa. It was given by Mirta Gomez at the beginning of the year for the Library of Congress. It was from the beginning of 2012 and I don't know how I missed it.
I have to say, I only know a little about Tumba Francesa and am glad to know more.
