For country star Zach Bryan and the University of Michigan, there’s a magic number looming: 110,905. When Bryan performs at Michigan Stadium on Sept. 27, that's the attendance figure he’ll need to exceed to break the record for the biggest ticketed concert by a single act in U.

Zach Bryan, the 28-year-old Oklahoma star, scored a No. 1 album with 2023's self-titled "Zach Bryan" album. Last year's "The Great American Bar Scene" debuted at No. 2 on Billboard's Top 200 albums chart.
