Krampus at Majestic Repertory Theater

The Krampus was mostly an old-world thing until recently. The goat-horned pagan beast has been skulking through the winter dreams of Germans and Eastern Europeans since times medieval—punishing wicked children with a whip or incarceration in a burlap sack, or occasionally chasing busty women with his long pink tongue lolling away. In the mid-2000s, “The Devil of Christmas” came to America in a multimedia blitz: in a popular 2004 holiday card set, in episodes of The Venture Bros. and The League, and in a 2015 comedy-horror film starring the eminently punishable Adam Scott.

Now, inevitably, Krampus has come to Vegas. Majestic Repertory Theatre’s immersive production of Krampus, intended for audiences 21 and older, will not be held in the company’s Main Street space; rather, it’ll be in a private residence, the location of which you’ll only learn the day of the show. Each performance is limited to an audience of 14, so when the Krumeich family and their “guest” invite you in, you can safely expect to meet … everyone. Hurry—it’s selling out. December 23, Various showtimes, $35. –Geoff Carter
