Singer-songwriter IU will hold a concert to celebrate her 15th debut anniversary in September, her agency EDAM Entertainment said Tuesday.  
 
Titled “I+UN1VER5E,” the concert will be held at the KSPO Dome in Songpa District, southern Seoul on Sept. 23 and 24.  
 
The title refers to IU and Uaena, her official fan club, and the time they’ve spent together in the fandom universe, according to the agency. Letters I and S, replaced by 1 and 5, refer to the 15 years the singer has spent with her fans since her debut in 2008.
