Panic! at the Disco will headline the 2025 When We Were Young festival in Las Vegas with Blink-182.

The nostalgic emo and rock fest will take place on October 18, 2025 and will also include performances by Weezer, Avril Lavigne, the Offspring, the Used, All Time Low and Knocked Loose.

It’s unclear if the performance will be a reunion for the band, which essentially became a solo project for Brendon Urie in 2015. Urie announced in January 2023 that he would be quitting Panic! at the Disco to focus on his family and newborn child. When We Were Young marks Panic! at the Disco’s first show since March 2023.

Variety has contacted Panic! at the Disco reps for clarity.

Panic! at the Disco will perform the 2005 album “A Fever You Can’t Sweat Out” (featuring the band’s signature song “I Write Sins Not Tragedies”) in its entirety.

The festival also features “rare performances” from Never Shout Never, the Cab, the Rocket Summer and Jack’s Mannequin. The lineup also includes the Gaslight Anthem, Bad Religion, Yellowcard, Simple Plan, Taking Back Sunday, the Story So Far and Never Shout Never.

Tickets for When We Were Young go on sale on November 1. Information about purchasing can be found on the festival website.

Perhaps derived from the famous Killers song, When We Were Young began in 2017 in Santa Ana, California, before becoming a full-scale production at the Las Vegas Festival Grounds. Previous headliners include My Chemical Romance, Paramore and Fall Out Boy.
