At nearly 40, perennial country partyboy Luke Bryan’s still out for fun, but he also sounds like he's rethinking what that word means. Following what he says is the last of his Spring Break EPs, Kill the Lights opens with the backroads rallying cry of “Kick the Dust Up” and follows with the Hall & Oates-style slink of the title track before settling into “Strip it Down,” a ballad about marital romance that doubles as a metaphor for simplicity: “We both know that we lost it somehow / Let’s get it found / Strip it down.”
