Jason Isbell took home two trophies at Wednesday (Sept. 21)'s American Music Awards and celebrated by completely owning Robert's Western World with a surprise set.

Isbell won Album of the Year for Something More Than Free as well as Song of the Year for "24 Frames" during the 15th annual awards ceremony, held at the Ryman Auditorium, and after a high like that, who could expect him to go home? Instead, Isbell walked across the alley that separates the Ryman from Nashville's famous Broadway bars and onto the stage at Robert's Western World. Readers can press play above to watch Isbell and wife Amanda Shires cover Merle Haggard's "Sing Me Back Home" during that set. Accompanied by Shires on fiddle and backing vocals, as well as the Robert's house band, Isbell completely slayed the performance of Haggard's 1968 hit.

After his performance, Isbell stepped back so that his wife, a solo artist in her own right, could sing a Haggard tune -- and then the duo gave up the stage to none other than Steve Earle, who belted out Waylon Jennings' "Are You Sure Hank Done It This Way." Saving Country Music reports that the crowd at Robert's during the show included famous faces such as Cary Ann Hearst of Shovels & Rope, Jack Ingram and even Sam Palladio of Nashville fame.

The 2016 Americana Music Awards included other big winners such as Chris Stapleton for Artist of the Year, Margo Price for Emerging Artist of the Year and Emmylou Harris and Rodney Crowell for Group / Duo of the Year. The 2016 Americana Music Festival, which takes place yearly in Nashville, runs through Sunday (Sept. 25).
