"I got a mouth like a sailor, and yours is more like a Hallmark card," snarls Lambert on "Only Prettier," one of several songs that cement her role as Nashville's best tough chick. Her vengeful side gets plenty of play on Revolution there's a dig at country radio as well as a scorched-earth love song co-written with her boyfriend, Blake Shelton but there are also prolonged episodes of maturity, from the pointed cover of Fred Eaglesmith's "Time to Get a Gun" to "Dead Flowers," a song that proves she can build an emotionally convincing performance atop even the lamest of metaphors. With each album Lambert gets better and inches closer to becoming country's next great superstar.
