Cesaría Évora is from Cape Verde and became an international star when she was 47 years old - that is 20 years ago.
La Diva Aux Pieds Nus (The Barefoot Diva) is the name of one of her albums.
You can watch/hear her singing Besame (the only song she did in Spanish) on this video. I love that song, and she does it so well :-)
Have a great weekend!
