During Zach Bryan’s performance at Lincoln Financial Field in Philadelphia on Wednesday (August 7) the country star was joined by some very special guests. The Lumineers and Shane Gillis both shared the stage with Bryan during his set, but it was the appearance by Bruce Springsteen that thrilled the sold-out crowd the most. The pair of music superstars performed a duet of Springsteen’s Nebraska standout, “Atlantic City,” as well as “Sandpaper,” their collaborative track on Bryan’s new album, The Great American Bar Scene. Earlier in the show, Bryan and the Lumineers performed their 2023 collaboration, “Spotless,” and the Denver band stuck around to later join in with both Springsteen and Gillis to help Bryan triumphantly close out the show with his 2020 fan favorite, “Revival.” (People)
