Acoustic interplay generates an electric charge as guest musicians join Marty Stuart and his Fabulous Superlatives for a concert that puts the pedal to the metal of bluegrass tradition. The hometown crowd at Nashville's Mother Church of Country Music (the same stage on which a 13-year-old Stuart made his Ryman debut accompanying Lester Flatt on the mandolin) spurs the band to peak intensity. With stellar support from fiddler Stuart Duncan and banjoist Charlie Cushman--and a guest appearance by master Dobroist Josh Graves--Stuart and band explore and extend the dynamics of bluegrass, from familiar fare such as "Orange Blossom Special" and "The Great Speckled Bird" through the harmony-laden balladry of "Homesick" and the honky-tonk heartbreak of "The Whiskey Ain't Workin' Anymore" and "Hillbilly Rock," with the latter providing the closing kick to a particularly lively evening. --Don McLeese
