Start with traditional-sounding fiddle tunes, add some jazzy keyboard riffs, some spicy clarinet licks, and some hot hand-drumming, and you've got the New Rhythm Rangers. Barb Kirchner (keyboard, percussion) and Brett Bowen (dumbek, tupan) make up the rhythm team while Mark Brissenden (fiddle, banjo) and Amy Self (clarinet, recorder, mandolin) ride the range from old-time to world music to neo-contra, leaving no prisoners (but lots of smiling dancers) in their wake.
