The country-pop trio took to the stage at the iHeartCountry Festival, a music experience presented by AT&T at Austin's Frank Erwin Center. They opened with their smash hit "Life Is A Highway," on Saturday night before slowing things down with their emotional ballad "What Hurts The Most" from 2006's Me and My Gang.
You can re-live the iHeartCountry Festival during the special TV broadcast on May 19 at 9 p.m. ET/PT on Audience via DIRECTV channel 239, DIRECTV NOW, or U-verse channel 1114.
