Zach Bryan John Mayer Draw Record Crowd Michigan Stadium First Concert

On Sept. 27, 2025, Zach Bryan headlined—and John Mayer opened—a sold-out, first-ever major concert at Michigan Stadium in Ann Arbor (the Big House). Organizers reported more than 112,000 tickets sold, which would surpass George Strait’s previous U.S. ticketed-concert record of 110,905, and some outlets said the show sold out in as little as 2.5 hours. The seven-hour, five-act bill drew huge tailgates, brisk merchandise sales and widespread local excitement, with Mayer praising Bryan onstage. University officials signaled the stadium will host more concerts selectively to drive revenue as the athletic department absorbs new expenses such as athlete revenue-sharing. Local commentators and reporters described the night as a historic moment that expands Ann Arbor’s musical footprint and marks a new chapter for the 98-year-old venue.
