The 2022 edition of the pop-punk/emo-leaning When We Were Young festival hasn’t even happened yet — it’ll go down on three different days later this month — but the organizers have already revealed the lineup for 2023’s event, which will take place on October 21 at the Las Vegas Festival Grounds. It’s headlined by Green Day and Blink-182 — the latter just announced today that they were reuniting with Tom DeLonge, and WWWY is just one stop on a massive global tour.
