Rhythm, Roots and Blues

For over four decades, blues guitarist Taj Mahal has taken the blues to places it's never been before, including Hawaii, Appalachia, and Mexico. On today's show, the veteran bluesman talks about his global career and star-studded new album, appropriately named "Maestro." Also: The Carolina Chocolate Drops is a young trio from the Piedmont region of North Carolina that's reviving the neglected African-American string band tradition. The group joins us with a live performance.
