Dong Xi is a world music duo focusing on presenting a new experience in collaboration with individual unique tastes in a "controlled improvisation" setting. Its name derives from the identities and backgrounds of its composing musicians. Also, it represents an element of surprise from the Chinese idiom "feint to the east but attacked in the west." This is one of their signatures in their music and represents their unique and interesting ways of creating musical dialogue for their music. They use the subtleties of the Chinese dulcimer to blend seamlessly with the world music percussion to create an elaborate and amazing duo improvisation.
