Ann and Phil Case for ages 18+ will be held at the Yellow Springs Community Library on Sat., May 20, from 1-2 p.m. Ann and Phil Case specialize in singing old-time Appalachian duets, old-fashioned parlor songs and Depression-era tunes as well as performing old-time instrumental duets. Ann sings with a rare natural sweetness and plays back-up guitar and fiddle. Phil plays guitar, Dobro, clawhammer banjo, mandolin and harmonica, and provides harmony vocals. Their sound draws upon the influences of the Carter Family and their contemporaries, early country blues, ragtime, and traditional ballad singing.
