The country music extravaganza will bring together top music acts for one incredible three-hour show on 3 August; it was filmed at Nashville's Nissan Stadium during June's annual live festival.

Alongside Carrie and Luke will be Jason Aldean, Kelsea Ballerini, Brothers Osborne, and Kane Brown, sand duets from the likes of Wynonna Judd and Carly Pearce, Dustin Lynch and MacKenzie Porter, Cole Swindell and Lainey Wilson, and Elle and Ashley McBryde.
The event will be hosted by Elle and Dierks Bentley. "I think Elle brings so much to the table," said Dierks.
"Onstage she’s just a riot and also super talented - a great combination of talent with comedic humor. A lot of spontaneous moments between the two of us and just a lot of laughs."
"I am co-hosting this whole shebang," added Elle. "Not only do I get to do it with my buddy Dierks, I also get to see all these incredible performances and be a part of a big party!"
Luke and Carrie have been friends for years
"When Dierks and Elle first performed together at Fest in 2016, I knew they had something special,” said CMA Fest Executive Producer Robert Deaton.
"The festival itself may be over, but thanks to these two, along with a solid slate of performances and special collaborations, the party continues in homes across America. It was a fun challenge to think differently with our setup these last two years, but it felt great to be back with a full house at the stadium."
Lady A will also be performing, and previously told HELLO what fans can expect from their performance. "I definitely feel like the outdoor festivals are all about the whole experience," singer Hillary Scott told us.

"As a fan, going to those shows it's all about just who you go with, you gather with your friends and you either want to sit in the seats or you want to sit on the lawn, it kind of depends on the vibe of the group."
She added: "So, for us, from the artists' perspective, we definitely play to a higher energy."
Revealing that music lovers will hear a back catalog that will include several of their best-loved hits, Hillary added: "You play all the songs that everybody knows because everyone is a part of making this night fun and being a moment. You definitely keep the energy up and want to create those moments."
