CASPIAN HAT DANCE
9 p.m., White Water Tavern. $5.
And now for something completely different: From Amsterdam come five shirtless, be-wigged, funny-sunglass-wearing multi-lingual multi-instrumentalists. Who dabble in gypsy music, klezmer, “misbehaved village wedding music” and Southern Italian pizzica (Italian folk dance). Who sing in Dutch, English, German, Hungarian, Italian, Romani, Spanish and languages of their own creation. But, mostly, at least based on their material available online, who play instruments like the accordion, bass, guitar, washboard and a slew of more exotic ones — the darbuka, daf, dum-dum, charango and quena. In its web bio, the band prides itself for hard, indiscriminate touring, boasting that it plays everywhere from bars to squats to your rooftop. All sounds like the perfect mix for White Water, where stomping is always encouraged.
