WATCH: Hauntingly beautiful performance by Kentucky choir

A choir in Louisville, Kentucky gave a hauntingly beautiful performance for an entire hotel when they sang the Star-Spangled Banner.

Each year, the Kentucky All-State Choir gathers at the edge of the balcony of their hotel to end the day with the national anthem during their conference and this year was no different.

Their vocals filled the air at the Hyatt Regency, in the yearly, time-honored tradition and to the delight of all the guests.

Several videos of the performance were shared on social media, including this one by Garrett Mager, which was viewed by millions of people and shared nearly 100,000 times. 

“Had a proud #American moment tonight,” he wrote. “Woke up in my hotel hearing a lot of noise outside in the lobby. I went out and found this.”
