Cole Swindell and Dierks Bentley took the 2017 ACM Awards stage on Sunday night (April 2) to perform “Flatliner,” their collaboration from Swindell's second album You Should Be Here.

From start to finish, it was clear that the guys were having a ball on stage, working the crowd, playing off one another and generally bringing the party to the 52nd annual ACMs. Swindell and Bentley's performance of "Flatliner" was Swindell's first full performance on the ACM Awards, and his initiation into being part of the show was made all the better by Bentley.

"This is my first full performance on the ACM Awards show, and to get to sing with someone like Dierks Bentley, my tourmate and someone who has been a big influence on me and my music, [makes it] a special, special night," Swindell told ET before the awards show, adding, "I'm going to be excited, maybe a little nervous, but it’s going to be awesome."

The lyrics of "Flatliner" talk about a woman who's "a little heart-stopper," and its newly released music video captures the energy created when Bentley and Swindell come together onstage. Swindell's currently opening for Bentley’s What the Hell World Tour, along with Jon Pardi.

“I couldn’t be more proud to be on tour with anybody," Swindell says of Bentley.
