Episode 325: In 1972, a 19-year-old bass player and natural born singer from Kentucky and Indiana auditioned for an emerging band called New Grass Revival. Over almost 20 years, John Cowan would be the voice of that ensemble, through mega tours supporting Leon Russell, improbable country radio success, and the emergence of a whole new genre of roots music they gave a name to. NGR got Cowan into the Bluegrass Hall of Fame, but there's so much more - a mighty solo career, abundant collaborations, and a steady gig in the Doobie Brothers. Now his latest project is the new band The HercuLeons, a Nashville supergroup with fiddler/singer Andrea Zonn. Here, John covers his life in music. Next week, Andrea Zonn gets her turn.
