Joseph Decosimo learned the old-time fiddle and banjo at the feet of the masters, studying with the Kentucky master Clyde Davenport from an early age and earning a PhD in traditional music from the University of North Carolina. Well-connected among traditionalists, Decosimo also taps into some non-old-time-y talents for this record, the jazz guitarist Matthew O’Connell, Andy Stack of Wye Oak and Helado Negro on bass and Beirut’s Kelly Pratt on horns. The result, Fiery Gizzard, is a full, rich, vibrant music that feels aligned with history but not confined by it.
