There is plenty to like about the first season of ABC’s prime-time drama Nashville. The centerpiece, of course, is music. Actors Connie Britton (Rayna James), Hayden Panettiere (Juliette Barnes), Charles Esten (Deacon Clayborne), Clare Bowen (Scarlett O’Connor), Sam Palladino (Gunnar), and others actually perform the songs in the series backed by a host of ace studio players. T Bone Burnett is Nashville’s music producer, and he’s enlisted some of Music City’s finest songwriters and the help of longtime friend Buddy Miller to co-produce (and perform on) most of the songs here.
