Louisiana native Alecia Nugent has ascended swiftly to the upper ranks of bluegrass—so quickly, in fact, that the title of her third album is a gentle self-mockery of her superstar status inside the genre. But the focus of Hillbilly Goddess is resolutely down-to-earth, from the autobiographical “The Nugent Family Band” (which she wrote with Tom T. and Dixie Hall) to the wistful ballad “Already Home.” Producer Carl Jackson keeps the sound clear and simple, tastefully accenting a set of songs that occasionally veer into stickily sentimental territory but, for the most part, live up to this hillbilly goddess’ growing reputation.
