CMA Music Festival is called “Country’s Biggest Party” and there’s a very good reason for that!

Each June, country music’s biggest US stars perform blistering 5-6 song sets to over 50,000 people each night, over four nights at Nissan Stadium, home of the Tennessee Titans NFL team.

And last week, US free-to-air network ABC telecasted a prime-time festival special, featuring performances and other memorable moments from the festival, which gets bigger and bigger each year.

Stars such as Luke Bryan, Carrie Underwood, Kane Brown, Old Dominon, Blake Shelton, Maren Morris, Brett Young, Pistol Annies and Brothers Osborne took to the stage for this year’s event.

Unannounced artist collaborations are always a CMA Music festival highlight.

And this year was no different.

The Chainsmokers joined telecast co-host Kelsea Ballerini (pictured) to perform their global pop hit ‘This Feeling.’

Keith Urban joined Lil Nas X and Billy Ray Cyrus for a special performance of ‘Old Town Road.’

And Luke Combs joined childhood hero Tim McGraw, who with Ballerini will be in Australia this September for the very first C2C Australia festival, for a performance of McGraw’s hit song ‘Real Good Man.’

The festival TV special hasn’t aired in Australia as yet, but the CMA have kindly helped out fans across the world, desperate to catch some of the action, by posting a bunch of festival highlights on Youtube.

Here are just 8 of the most memorable ones!
