WASHINGTON — Lexi Mae Walker, the 14-year-old Utah singing sensation, expects to feel a bit like Cinderella when she sings while Vice President-elect Mike Pence and his wife dance at an inaugural ball on Friday night after Donald Trump is sworn in as the 45th president of the United States in Washington, D.C.

"It's really big, and it's really cool, because it's my first ball," the teenager said. "I think I'm going to have a major Cinderella complex. It's pretty exciting."

Walker landed in Washington on Tuesday night with another Utah group, the Piano Guys, who also will play at "Liberty and Freedom: The Official Presidential Inaugural Balls."

The Piano Guys will perform at both the Liberty and Freedom balls. Walker will perform at the Freedom Ball.

"I'll be singing a couple of songs for sure," she said, "possibly a third song. But I'll be singing the songs for the vice president's first dance. It's very cool. When we first heard about the opportunity, I was really excited. It'll be sweet."

The Freedom Ball will feature another Utah teen, Olso, a DJ big enough by night to land a gig taking over an hour's worth of music Friday night.

By day, 16-year-old Cache Olson is a student at Lone Peak High School in Highland, Utah, who is going to Preference back home on Saturday night.

To top it all off, the self-described DJ/producer/artist will get his Eagle Scout Award on Sunday night.

"This is kind of a crazy week," admitted Olson, who goes by Olso when he DJs.

Olson will play walk-in music before the ball, then take over and produce a DJ set from 10 p.m. to 11 p.m. to close the event. He'll feature six or seven of his own songs in a mix of about 35 he'll play during the set.

"This is definitely the biggest thing I've done," he said. "I've been around the country quite a bit, but this is the coolest set I've had."

Olson's inaugural gig was announced over the intercom at Lone Peak High on Tuesday morning, leading to an outpouring of support from teachers and students.

"We are so proud of Cache and excited for him to have this opportunity," school principal Rhonda Bromley said in an email. "I know that he will do a great job reprenting Lone Peak."
