The New York City skyline isn't complete without the magical changing lights of the Empire State Building, especially around the holidays. This year, platinum-selling acapella group Pentatonix is upgrading the long-standing tradition dating back to 1972 with their very own holiday light show.

Starting Dec. 21 until Dec. 24, a display of LED lights choreographed to their Grammy-nominated track "Dance of the Sugarplum Fairy" will tower over the city along with a simultaneous broadcast on iHeartMedia platforms every night at 7 p.m. ET. To get fans pumped for the light show, PTX performed at the ESB's lobby and made a surprise appearance atop the giant skyscraper on Dec. 10. Of course, InStyle followed the group all the way to the top and got a breathtaking interview overlooking all of Manhattan.

Their recent Grammy nomination isn't their first go-around with the prestigious honor. PTX already won a Grammy for their arrangement of "Daft Punk" earlier this year. They've also amassed more than 9.5 million subscribers on YouTube, gaining over 1.2 billion views. "Still, we had a rocky start. No one believed that acapella could make it in the mainstream because it never has. One of our biggest challenges has been getting the industry to believe in us," shared member Mitch Grassi.

They'll continue to take their determination into the new year. "In everything we do, it's important to keep motivation and be inspired," said member Kirstin Maldonado. At the same time, Scott Hoying also pointed out: "Don't let the holidays stress you out too much! Consciously let yourself enjoy everything around you. The beautiful holiday decorations, your family, the music, the cold air. It's a beautiful time of year, and that shouldn't be forgotten." Cheers to that, we could all use a reminder from time to time. PTX's positive energy and light show will surely spread some holiday cheer. New Yorkers, don't forget to look up starting at 7 p.m. tonight and for those of you who can't make it to the city, a video of the show will be posted on YouTube, so stay tuned!
