It was 1990 when he, Dan Seamans and Kenny Wollenson sprung the New Klezmer Trio on an unsuspecting world. No doubt, there were earlier shenanigans we haven’t been told about; and many rivers have been crossed since. Here’s the grand vizier’s brand new bag, prospectively great we’re certain–in cahoots with some likely co-conspirators, viziers of their own realms and tricksters all. Knock on wood.
