The 2019 ACM Awards will once again feature the awards show's ACM Flashbacks series, featuring some of the genre's most-revered artists and the music that continues to speak to performers and fans alike today. This year, the event's ACM Flashbacks will include a collaboration between iconic country star George Strait and Miranda Lambert, who is the most-awarded artist in ACM history, with a whopping 32 trophies to her name.

The superstar duet is just one of a series of onstage collaborations planned for the 2019 ceremony. Also included in the 2019 ACM Flashbacks will be a performance from Brooks & Dunn (who held the title of most-awarded act until 2018, with 29 trophies) alongside the newly crowned 2019 New Male Vocalist of the Year, Luke Combs.

Many more country stars will come together for duets during the evening's festivities. ACM Dick Clark Artist of the Decade honoree Jason Aldean will perform with Kelly Clarkson, Dierks Bentley will join forces with Brandi Carlile, Maren Morris will team with Brothers Osborne and Eric Church will take the stage with 2019's New Female Vocalist of the Year, Ashley McBryde.

Both Aldean and Clarkson will be pulling double duty during the lineup of duets, as both will return to the stage for a second collaboration, Aldean with Florida Georgia Line and Clarkson with Dan + Shay. Additionally, Kane Brown will take the stage for a very special cross-genre performance alongside multi-plantinum award-winning superstar Khalid.

A star-studded lineup of 2019 ACM Awards performers has already been revealed, with more artists to be announced in the week ahead. Reba McEntire, who is also among the list of acts set to take the stage, will host the ceremony.

The 2019 ACM Awards will take place on Sunday, April 7 in Las Vegas, Nev. at the MGM Grand Garden Arena. The show will air live on CBS beginning at 8PM ET.
