The article on the Bata drums has been updated. I incorporated more of the Spanish version by Olavo Alen Rodriguez and cleaned it up a bit. The batá drums are the sacred instruments of Cuban Santería. They are made up of three hourglass-shaped drums of different sizes that perform specific musical functions. They are important culturally as well as influencing popular Cuban music. Here is a link to the article: Bata Article by Olavo Alen Rodriguez.
