Carrie Underwood's "Heartbeat" made its television debut at the 2015 American Music Awards.

The country superstar took the stage in a stunning, off-the-shoulder red dress to sing the sweet ballad. Smoke billowed across the stage floor as she and her band performed the tune amid dozens of white candles and red lanterns, in front of a simple, starlit backdrop.

“Tonight I wanna drive so far we’ll only find static on the radio / We can’t see those city lights / And I love the way you look in a firefly glow,” Underwood sings during the song’s chorus. “Saying everything without makin’ a sound / With a river rollin’ the background / Underneath a harvest moon / Standin’ on your shoes in my bare feet / Dancin’ to the rhythm of your heartbeat.”

"Heartbeat" is from Underwood's latest album, Storyteller.

“There are some things on there that are definitely familiar, but there’s a lot of growth that has happened, as well,” Underwood explains of the new disc. “It’s going to sound a little bit different — still the things that fans will obviously know is me. I’m not going crazy or anything, but it’s a little bit of a shift.”

Underwood is nominated for one American Music Award this year, for Favorite Female Artist -- Country, along with Miranda Lambert and Kelsea Ballerini.
