CMA Music Festival Special: What to Expect from the Star-Studded Show

Keith Urban, Carrie Underwood and Luke Bryan are among those performing.

"We were a little shaky and nervous the first year, but now we feel really comfortable, and it's been a blast," one of LBT’s guitarists, Jimi Westbrook, told ABC News. "It's such a cool thing 'cause we're here for the entire thing. We get to see everybody that's here and hang out with them and listen to them play. It's just a great experience."

The performances were filmed during June's four-day CMA Music Festival in Nashville.

"There are a lot of festivals out there. There's a lot of things people can go to, but this is very much about just a love letter to the fans, in my opinion, and saying thank you," said Chesney.
