The Nashville Sound is the first official Jason Isbell and the 400 Unit album since 2011's Here We Rest. The 400 Unit features Derry Deborja (keyboards), Chad Gamble (drums), Jimbo Hart (bass), Amanda Shires (fiddle) and Sadler Vaden (guitar). The Nashville Sound was recorded at Nashville's legendary RCA Studio A and produced by Grammy Award-winner Dave Cobb, who also helmed Isbell's Grammy-winning 2015 album Something More Than Free and his 2013 breakthrough Southeastern. "Lyrics and melody are still the driving force behind what we're doing, but this time around, there's more of a rock ‘n' roll influence," Isbell says. "You might shed some tears, but for once, there's a chance you might also dance a little."
