The Gullah people are descendants of African slaves who have established a unique culture in the islands and lowland regions of South Carolina and Georgia. Their various folkways have attracted the attention of folklorists and anthropologists for many years, and for this album the Charleston-based jazz ensemble Ranky Tanky has adapted a set of traditional Gullah songs — not turning them into jazz numbers, but rather letting the songs themselves shape the way they use their instrumentation. A few of these songs will be familiar to many listeners: a very different version of “O Death” has been part of the bluegrass gospel tradition for some time (and was prominently featured in the movie O Brother, Where Art Thou?), and both “Turtle Dove” and “You Gotta Move” have made their way into the broader popular culture. These arrangements are idiosyncratic and make no attempt to be “authentic”; instead, they’re modern interpretations and deeply personal — and they’re both fun and moving.
