The Las Vegas Strip has more than its share of America’s Got Talent alumni, but Lindsey Stirling is different—and AGT wasn’t even her most recent appearance on a well-known talent competition show. The 31-year-old violinist and composer took second place on the most recent season of Dancing With the Stars, and there’s a good chance she would have won had she not been pulling double-duty, rehearsing for her current tour behind October album Warmer in the Winter during Dancing’s final three weeks. “It was exhausting, to say the least,” Stirling told Tulsa World. “Touring seems so easy now. It’s almost relaxing because, all of a sudden, I have all these hours in a day to fill up. I almost feel lazy.”

Lazy is hardly the word to describe an ambitious artist who incorporates classical, pop, rock and electronic influences into her sound. She won her second Billboard Music Award for Top Dance/Electronic Album this year for Brave Enough. Winter marks her first foray into Christmas music, highlighted by a cover of “You’re a Mean One, Mr. Grinch” with 18-year-old singer/songwriter Sabrina Carpenter, and the original title track featuring Trombone Shorty. Expect some unique twists to traditional holiday music when Stirling’s tour lands at the Cosmopolitan this month. December 22, 8 p.m., $30-$300, the Chelsea, 702-698-7778.
