A leading figure of the Asian American Jazz movement, the Chinese-American violinist Jason Kao Hwang blends American music with Japanese, Korean, and Chinese forms. But that’s not enough culture-crossing for Hwang, who keeps seeking out new traditions to drop into his melting pot. As luck has it, his D.C.-based friend Ayman Fanous does pretty much the same thing. The Egyptian-born improv guitarist touts flamenco player Paco de Lucia and free-jazz mastermind Ornette Coleman as major heroes, and channels his Mediterranean roots by (among other things) doubling on the Greek bouzouki. Put Hwang and Fanous together, and you have an improvised sound that’s even more textured in its use of cultural traditions than it is in its interplay of string instruments. Does playing in an Episcopal church add yet another layer of fusion? That’s TBD.

HWANG AND FANOUS PERFORM AT 8 P.M. AT ST. MARY’S EPISCOPAL CHURCH, 728 23RD ST. NW. $15 SUGGESTED DONATION. (202) 333-3985.
