All Time Low proudly carry on the sonically ambitious pop-punk legacy kick-started by Green Day in the '90s and continued by Fall Out Boy the following decade. Case in point: Although the Towson, Maryland quartet cut their teeth playing blink-182 covers, they've evolved into writing pop struts like "Monsters," which boasts a swaggering hip-hop bridge from the musician and producer blackbear. "We've never really featured a rapper on anything," vocalist/guitarist Alex Gaskarth told Apple Music about the 2020 single. "It's like, 15 years into a career, there's still some new things to try." That relentless quest for new sounds is nothing new for All Time Low, whose members—Gaskarth, guitarist Jack Bakarat, bassist Zack Merrick, and drummer Rian Dawson—started playing together in 2003 while they were still high schoolers. In 2007, the band released their most recognizable song, the pogoing emo staple "Dear Maria, Count Me In," and the brisk, breakdown-filled hit "Weightless" two years later. On subsequent albums, All Time Low eschewed genre boundaries, challenging perceptions of what a Warped Tour headliner should sound like as they explored twinkling, mandolin-heavy fare ("Missing You") and electronic-glazed pop-rock ("Dirty Laundry"). All Time Low are proof that enduring curiosity paired with a willingness to experiment is the ideal combination to extend pop-punk's vibrant legacy.
