Getting your Trinity Audio player ready... The Ukrainian port city of Odesa is known as the “Pearl of the Black Sea” for its urban planning and architectural aesthetic. It also has a rich tradition of humor, culture and music, which Kommuna Lux, an Odesa-based folk group, is all set to bring to Palo Alto. The band will kick off its West Coast charity tour with a concert at Oshman Family JCC on Sept. 26 before proceeding to other cities across and beyond California.
