It's 2005 again…again.

The annual When We Were Young Festival has just announced the lineup for the 2025 edition of their nostalgia-core extravaganza, which will take place on October 18th at the Las Vegas Festival Grounds.

Throwback headliners set to perform include pop-punk pioneers Blink-182 (with tracks from “Enema Of The State” and “Take Off Your Pants and Jacket”) and baroque emo heroes Panic! At The Disco (which performs “A Fever You Can't Sweat Out” in its entirety after disbanding in 2023) features chart-toppers Weezer, riot grrl Avril Lavigne and “Pretty Fly” rockers The Offspring.

All Time Low, Knocked Loose, The Gaslight Anthem, Jack's Mannequin and Bad Religion are just some of the other big names on the aughts-tastic list.

But wait! As with any good 2000s commercial, there's more.

Punk greats like The Used, Yellowcard, Simple Plan and Taking Back Sunday will also rock at WWWY '25.

And if you look closely at the festival poster, you'll see that the “Plain White T's” from “Hey There, Delilah” are also featured.

A total of 53 anti-establishment acts will rock Sin City over the course of the one-day jamboree.
