The nostalgia-packed When We Were Young Festival is officially doubling up in Las Vegas this year. After the Saturday, October 18 date sold out in advance, organizers have announced a second show on Sunday, October 19, featuring the exact same stacked lineup at the Las Vegas Festival Grounds.

Headlining both days are Panic! At The Disco, who will perform their iconic debut album A Fever You Can’t Sweat Out in full, and blink-182, delivering a throwback set featuring hits from Enema of the State, Take Off Your Pants and Jacket, and Untitled.

The festival’s undercard is just as exciting, featuring Weezer, Avril Lavigne, The Offspring, All Time Low, The Used, Knocked Loose, The Gaslight Anthem, Bad Religion, and Yellowcard. Fans can also expect rare performances from Never Shout Never, The Cab, The Rocket Summer, and Jack’s Mannequin, making it a must-attend event for pop-punk and emo lovers.

With the first date selling out quickly, fans will want to act fast when tickets for the second show go on sale this Friday, February 28, at 10 AM PT.

This year’s When We Were Young Festival is shaping up to be one of the biggest nostalgia-fueled events of 2025!
