The fourth edition of When We Were Young Festival will be headlined by Panic! At The Disco and blink-182 on October 18, 2025 at the Las Vegas Festival Grounds. The massive lineup includes performances from Weezer, Avril Lavigne, The Offspring, The Used, All Time Low, and more.

Panic! At The Disco return home to Las Vegas to celebrate the 20th anniversary of A Fever You Can’t Sweat Out by performing the album in its entirety along with more fan-favorite songs. As the saying goes, what happens in Vegas stays in Vegas, so their When We Were Young appearance will be the only chance to see Panic! back on stage.
