While there are plenty of spirited klezmer bands around, this multinational British-based ensemble flit across the diaspora landscape more convincingly than most. And there’s just enough of a hint of gypsy jazz to entice the Django crowd. The singer Cigdem Aslan adds depth to everything she touches, from the everyday to the tragic, but this is very much a collective effort. The kaleidoscope spins dizzily from Bulgarian to Greece, Odessa and beyond; violin, clarinet, accordion, guitar and mandolin take turns to lead the dance.
