Panic at the Disco & Blink-182 Headline 2025 When We Were Young Festival

When We Were Young’s fourth edition has revealed its full lineup with Blink-182 and Panic! at the Disco as headliners.

Panic! at the Disco plans to mark 20 years of A Fever You Can’t Sweat Out by playing it completely, while other artists like Weezer, the Gaslight Anthem, Avril Lavigne, the Offspring, and Knocked Loose will also join them in Las Vegas. The lineup poster is below if you want to see everyone who’s coming.

A surprising twist came when Brendon Urie announced last year that Panic! at the Disco was done for good. Their final performance happened in March 2023 in Manchester.

The next When We Were Young event is set for Saturday, October 18, 2025, at Las Vegas Festival Grounds. In past years big names like My Chemical Romance and Paramore have taken center stage there.

Fans sometimes wonder why bands break up only to come back again later—it’s a mystery!
