If the last decade has proved anything (besides the irrepressibility of the Bush dynasty), it's that Klezmer cannot die. Just when you think this folk music has bitten the dust, some New York musician or other comes along and resurrects it. The Klezmatics are a conglomeration of musical polyglots who stay true to Klezmer's dark, dance-happy heart while exploring the genre's outer limits. Each band member is part of the vibrant Downtown scene, including Matt Darriau of the Paradox Trio and Frank London of Hasidic New Wave. They're madly talented and irreverently traditional.
