The Black Swans, a touring trio all the way from Columbus, Ohio, tackle existential crises through a nuanced blend of folksy blues. Lead singer, Jerry DiCiccia’s dusky voice  skims each syllable of the band’s enchanting and adorned folk, as if on the edge of unknown depths. Noel Sayre’s crisp violin plays perfect counterpoint to DiCiccia’s voice, as the Swans, unafraid to embrace tradition one minute,  leave tradition behind the next.
