Les Yeux Noirs -- named after a Russian Gypsy tune made famous by Django Reinhardt -- was founded by fiddling brothers Eric and Olivier Slabiak to explore the connections between Jews and Gypsies, the Old World and the New. The band bounces easily from klezmer to Hungarian Gypsy music and jazz while nestling on a bed of subtle electronic samples. Sunday at Ashkenaz in Berkeley. 510-525-5054. (j. poet)
