Watch Zach Bryan Join Jason Isbell and the 400 Unit Onstage for 'King of Oklahoma'

Zach Bryan brought his Quittin Time tour to Detroit's Ford Field on Thursday night and took the opportunity to sing with the artist who calls one of the “greatest songwriters of all time”, Jason Isbell.

Isbell and the 400 Unit play a number of dates on Bryan's stadium tour, and near the end of the opening set, Isbell welcomed Bryan to the stage for a duet of “King of Oklahoma,” off Isbell's 2023 Weathervanes album.

“Thanks for letting me spoil your song Mr. Isbell. I respect you and care about your music more than life itself. It was a privilege and an honor to meet a hero,” Brian self-deprecatingly tweeted after the show. “Can't wait to hear it without my voice on the next one, we love you!”

Bryan plays the Buckeye Country Superfest this weekend in Columbus, Ohio, before linking up with Isbell in Foxborough, Massachusetts, next week for another Quittin' Time tour stop at Gillette Stadium on June 26. Isbell and Unit 400 are also opening Bryan's New Orleans, Houston, Tampa, and Arlington, Texas, dates later this summer.

Bryan also announced the release date of his next album: The Great American Bar Scene It arrives on Independence Day, July 4th. Prior to launch, 23 select bars in the US — including Barnacle Bill's in Rumson, NJ. Fox & Locke in Franklin, Tennessee; and McGlinchey's in Philadelphia — will debut the record.

“My intention with all of this is to give everyone an early taste of this album, but more importantly in the spirit of bringing people together for an unforgettable moment,” he said in a statement. “No matter how much I would kill to play all these timeless bars, it won't be possible. I'll visit a few off the list to have a drink with you.”
