"He ain't seen me crazy yet," Miranda Lambert sings of a no-good ex on the opening track of her sophomore album. The Texas firebrand ups the ante here, delivering a set that moves between the unveiled threats of "Gunpowder & Lead" and the tender balladry of "More Like Her." This is country music at its most manic, with Lambert capturing both the half-cocked highs and lovesick lows of the album's titular protagonist.
