Described as a "sometimes pensive, often poetic, and continually progressive folk-pop ensemble," Cincinnati-based Over the Rhine has been making music for more than 20 years. Fronted by Karin Bergquist's torchy, devil-may-care voice brimming with Midwestern soul, the band is led by brilliant keyboardist and songwriter Linford Detweiler who can seamlessly move from avant garde jazz to whisper-quiet folk subtleties to flat out rock. Over the Rhine may well be one of Americana's best kept secrets.
