Are these angels or high school kids?! 

Indiana resident Garrett Mager took to Facebook to share an incredible moment he experienced while staying at the Hyatt Regency in Louisville, Kentucky. 

He wrote, "Had a proud #American moment tonight. Woke up in my hotel hearing a lot of noise outside in the lobby. I went out and found this. The Kentucky State Choir Finals schools are all staying at my hotel. They decided to sing the National Anthem together on every single floor. #Amazing"

Check out the spectacular video of these talented choir students blending their voices together in the hotel's atrium. INCREDIBLE ACOUSTICS!
