With her third record, Miranda Lambert remains country's most refreshing act, and not just because she makes firearms seem like a matter-of-fact female accessory. The playlist is her most varied yet: "Airstream Song" is a string-band dropout fantasy that includes a nod to fellow "red-dirt girl" Emmylou Harris, while a redneck-surrealist cover of John Prine's "That's the Way That the World Goes 'Round" rocks enough to get the girl booked at Lollapalooza. Lambert's Second Amendment talk goes beyond posturing: "Time to Get a Gun" (by Fred Eaglesmith) is more about working-class powerlessness than being trigger-happy. And on "Maintain the Pain," she shoots her car radio. Hey, Nashville: What d'ya think she's sayin' there?
