“Ranky tanky” translates loosely as “get funky” in the Gullah dialect of the southeastern Sea Island region, and that’s exactly what this Charleston, SC-based quintet aims to do. They add a jazz backbone to traditional Gullah songs, from children’s game songs to ecstatic shouts to heartbreaking spirituals. Strongly infused with West African rhythms, it’s music that “makes you want to dance and sing along with hope” (Afropop Worldwide).
