When We Were Young, an annual music festival held at the Las Vegas Festival Grounds in Winchester, Nevada, on October 18, 2025, has announced its 2025 lineup of more than 50 pop-punk, emo and alternative rock artists.

This year’s festival will be headlined by Panic! At The Disco, who are coming out of retirement for a one-off performance of their iconic debut album “A Fever You Can’t Sweat Out.”

Joining them on the festival bill are Blink-182, Weezer, Avril Lavigne, The Offspring, The Used, All Time Low and many more acts that defined the early 2000s rock scene.

Where to buy When We Were Young tickets

Although the festival is completely sold out, general admission tickets and VIP packages can be purchased on secondary market platforms such as Vivid Seats SeatGeek and StubHub, which offer verified tickets with buyer guarantees.

At the time of publication, general admission prices start at $427 on Vivid Seats.

Fans can also sign up for the waitlist to add a day two on the When We Were Young website.

What is When We Were Young’s 2025 lineup?

One of the most exciting aspects of the 2025 When We Were Young festival is the reunion of Panic! At The Disco — the Las Vegas-based band that officially disbanded in early 2023.

After a successful run with seven studio albums, the group’s frontman, Brendon Urie, announced that Panic! would no longer be performing. However, for this special festival appearance, Urie will take the stage to celebrate the 20th anniversary of their breakthrough album “A Fever You Can’t Sweat Out.”

Fans can expect the band to perform the album in its entirety, including hits like “I Write Sins Not Tragedies” and “The Only Difference Between Martyrdom and Suicide is Press Coverage,” alongside other fan favorites.

Headlining alongside Panic! At The Disco will be pop-punk legends Blink-182. The band, who were also featured in 2023’s festival, will bring their high-energy performance to Las Vegas with tracks from classic albums like “Enema of the State” and “Take Off Your Pants and Jacket.”

Other notable performers include Weezer, Avril Lavigne, The Offspring, Yellowcard, Bad Religion, Knocked Loose, Taking Back Sunday, Jack’s Mannequin, The Gaslight Anthem, The Story So Far, Motionless in White, Ice Nine Kills and Plain White T’s, just to name a few.
