Before the first flash of flesh, the saucy vibe is set by a recorded preshow serenade of Blake Shelton’s “Kiss My Country Ass.” Behold Nashville Meets Naughty, aka “X” Country: A Kickin’ Topless Revue. Now just wait a country minute and yeehaw … flesh!

Expanding the “X” brand of sexy Vegas shows—including “X” Burlesque, “X” Rocks, “X” Comedy and “X” Burlesque University—the new countrified entry is a jam-packed, fast-moving series of sensual segments featuring a hot quintet of lithe, limber ladies performing to a soundtrack ranging from Hank Williams Jr. and Garth Brooks to Tim McGraw and Taylor Swift. Video screens framing the stage at the intimate Improv room add multimedia pizzazz.

With down-home delight (interrupted only by a comedy break from a rotating slate of stand-up funny folks), these very fit gals execute spirited choreography in thematic numbers, from the moment they materialize out of the darkness, in tight short-shorts, with backsides facing the audience. Within 90 seconds, their tops are doffed—a frequent occurrence over the next 70 minutes of thrusts, gyrations, line-dancing, two-stepping and butt-slapping.

One must smile during the number set to Carrie Underwood’s “Before He Cheats”—come on, who would cheat on any of these ladies? Working us into a lather, one dancer luxuriates in an on-stage shower to Patsy Cline’s “Crazy.” Another strips down from a wedding dress to The Band Perry’s “Better Dig Two,” and three gals frolic with a bed sheet to Lady Antebellum’s “Just a Kiss.”

After one dancer gets a bit suggestive with a stuffed horsey toy to Miranda Lambert’s “Little Red Wagon” and several more two-step to Gretchen Wilson’s “Redneck Woman,” segments swing from those set to Nancy Sinatra’s “These Boots Are Made for Walkin’” and Dolly Parton’s “9 to 5” to a sexy salute to baseball (yes, baseball) and, of course, the always reliable leather-and-whips routine. All of which amounts to just a fraction of the “X” Country action. Yeehaw, indeed, pardner!
