A “When We Were Young” music festival is happening, bringing back iconic emo and rock bands from the last two decades. Kicking off in Las Vegas on October 22, the emo-pop fest just released its lineup, featuring headliners My Chemical Romance and Paramore. More Gen Z and Millennial emo-pop favorites are also performing, including the All-American Rejects, Avril Lavigne, 3Oh!3, Jimmy Eat World, and more. The festival marks the first Paramore show since 2018, and clearly, young fans are pumped because tickets have already sold out shortly after going on sale. YPulse told you how Gen Z has been leading a #emorevival, and the When We Were Young fest is guaranteed to unite new and old fans alike. (Stereo Gum, CNN)
