The line-up for When We Were Young 2025 has been released – and, among them, the swift reunion of Panic! At The Disco, which disbanded in 2023.

Today (October 29), the festival shared its 2025 poster with a bevy of top-tier names, which include Panic! alongside Blink-182, Weezer, Avril Lavigne, The Offspring, Knocked Loose, and more.

In celebration of its 20th anniversary, Panic! At The Disco will perform their debut album ‘A Fever You Can’t Sweat Out’ in its entirety, along “with some of your other favorite Panic! At The Disco songs”, the band announces in an Instagram post.

The reformation of Panic! isn’t the only reunion at the festival next year: post-hardcore band letlive. have been added to its line-up as part of a “proper” farewell tour – as lead singer Jason Aalon Butler revealed earlier this year – along with Never Shout Never, Jack’s Mannequin, and The Cab. The Gaslight Anthem are also performing at the festival after reuniting in 2022.

Meanwhile, a wide spectrum of pop-punk acts are scheduled for When We Were Young, including All Time Low, Yellowcard, The Used, Simple Plan, Taking Back Sunday, Mayday Parade and The Story So Far. On the heavier side of things, there’s Alexisonfire, Ice Nine Kills, Motionless In White, Kublai Khan TX, Bad Religion, Beartooth, and Loathe.

Pre-sales begin this Friday (November 1) at 10am PT – sign up here to receive an access code in order to join. See the full line-up below.

This year’s When We Were Young saw a unique approach to its curation – most of its line-up performed an album from their respective discographies in full over two days.

Among the classic albums performed live were My Chemical Romance‘s classic 2006 album ‘The Black Parade’, Jimmy Eat World’s ‘Bleed American’, A Day To Remember‘s ‘Homesick’ and Dashboard Confessional‘s ‘Dusk And Summer’.

The festival’s official merch t-shirt also went viral after fans discovered several band names were misspelt on its print. This included The All-Amercian Rejects (The All-American Rejects), New And Glory (New Found Glory) and We Are In The Crowd (We Are The In Crowd).

Panic! singer Brandon Urie announced in January 2023 that he was ending the band after almost 20 years. He revealed that he and his wife Sarah Orzechowski were expecting their first child together, and said that he wanted to focus on his family.

Taking to Instagram after bringing the band’s ‘Viva Las Vengeance‘ tour to a close at the AO Arena, Urie wrote: “I’m overcome with gratitude. I just want to say thank you from the bottom of my heart. For the last 18 years, it’s truly been an experience that I’ll always be grateful for.”

Fall Out Boy‘s Pete Wentz discussed the band’s break-up with NME, saying he had “a lot of respect” for Urie making the call. “I think that as far as Brendon wanting to live a more private life and be a dad, in that regard a new chapter for him has started, which I can really appreciate being a dad [myself],” Wentz said.
