Nu-Blu’s heart and soul is husbandand-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. Zach McCracken (banjo) and Justin Harrison (fiddle/mandolin) round out the quartet’s warm, layered, American roots sound that builds to a full country 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.
