For the second year in a row, pop-punk is taking over Las Vegas. The When We Were Young Festival is bringing another slew of emo and pop-punk acts from the mid/late aughts to the Las Vegas Festival Grounds on Oct. 21 and 22, from Yellowcard to Rise Against to Green Day.

"Fat Lip" rockers Sum 41 are one of the 55 artists playing this year's iteration of WWWY, which will mark two of the Canadian group's final shows (in May, they announced they'll be disbanding after their current tour commitments). Though they've been touring for nearly 30 years, frontman Deryck Whibley tells GRAMMY.com that the front row "looks the same as it did in 2001."

"This music speaks to a younger generation, and the new generation always gets into it," he says. "There's just something about this kind of music that is youthful and exciting, and there's energy there. I think it's always going to be here."

In celebration of the 2023 iteration of When We Were Young Fest, Whibley put together a playlist of 15 songs by his fellow performers, including the Offspring, Blink-182 and the Ataris. Whether or not you're headed to Las Vegas, get your dose of pop-punk nostalgia on Spotify, Apple Music, Amazon Music, or Pandora.
