Hailing from Siler City, NC, the textbook definition of a picturesque small southern town, Nu-Blu’s heart and soul is husband-and-wife duo Daniel and Carolyn Routh. Carolyn’s caramel-coated soprano is one of the band’s defining traits, at times a tender lullaby, at times a freight train headed straight for you, but always unwinding a surprising tale. Daniel is the group’s backbone, a multi-instrumentalist and vocalist who also handles band management. Calder Baker on vocals and banjo, and Justin Harrison on fiddle/mandolin round out the quartet’s warm, layered, American roots sound. Together they deliver upbeat, blazing-fingers pick work just as well as gentle, heartwarming ballads, and they do it all with a natural togetherness that can’t be faked, forged over hundreds of shows on the road.

Sally’s Suppers begin at 5 p.m.
