Two of the most powerful voices out there recently teamed up for their first duet.

John Legend and Carrie Underwood released “Hallelujah” at the end of November, written by Legend and Toby Gad (who previously wrote “All of Me”).

In the official music video that was released on Facebook, Underwood sings alongside Legend on a piano while it snows on them in an unused country cottage.

The song was also picked for the Empire State Building’s annual music and light show.

The full show will air from Dec. 19 until Christmas day each night at 8 p.m. ET. Those not in New York can watch here.

A preview was released ahead of time.

“I love this song because I feel like it encompasses so much about Christmas,” the country singer said. “You have this love aspect of it, it just feels like Christmas, it just makes you smile and to say ‘Hallelujah’ is just beautiful.”
