For two Okinawan women, drumming is the ultimate form of expression and a symbol of the dialogue they believe is essential to achieve world peace.

Chisato and Ayano Arakaki, both in their 30s, came to this realization in the course of composing music for a new production titled "War and Peace."

The sisters are key members of Zampa Ufujishi Daiko, a troupe of professional "taiko" drummers from the Okinawa village of Yomitan, where U.S. forces landed in April 1945 at the onset of the bloodiest battle in the Pacific during World War II.
