Meng Su and Yameng Wang are rapidly becoming California celebrities. Now in their second year as artists-in-residence for S.F. Performances they have been building new audiences for the guitar with regular performances and classes in public schools and community centers throughout the Bay area. Their repertoire has an exciting world music flavor featuring everything from such composers as Brazil’s Sergio Assad and China’s Tan Dun to sensitive interpretations of Spanish classics and the music of J.S. Bach. The Duo repeats this concert a week later for the Sacramento Guitar Society.
