Jerrod Niemann and Kix Brooks performed together for the 2014 American Country Countdown Awards.

The two hitmakers performed an acoustic version of the Brooks & Dunn hit 'Rock My World (Little Country Girl),' from the duo's 'Hard Workin' Man' album.

The ACC Awards are tallied in part from radio airplay, along with touring statistics. Brooks serves as the weekly host of the American Country Countdown, a position he has held since 2006.

Niemann was nominated for an ACC Award for Song of the Year, for his single 'Drink to That All Night,' from his 'High Noon' album.
