Rhiannon Giddens is an American artist of folk and traditional music, played on fiddle and banjo. Francesco Turrisi is an Italian pianist and percussionist well-versed in jazz, early music and Mediterranean music. At first blush, their worlds don’t overlap. But at a chance musical meet-up in Ireland, they found that her 19th century American minstrel banjo tunes and his traditional Sicilian tamburello (tambourine) rhythms fit very naturally together.
