With their emo-punk songwriting, theatrical vocals, and neo-goth appearance, My Chemical Romance rose from the East Coast underground to the forefront of modern rock during the early 2000s. They found mainstream success in 2004 with the release of their platinum-selling sophomore album and major-label debut, Three Cheers for Sweet Revenge. Two years later, they released the ambitious rock opera The Black Parade, which was certified triple platinum and included the hit singles "Welcome to the Black Parade," "Famous Last Words," and "Teenagers." The narrative-driven Danger Days: The True Lives of the Fabulous Killjoys appeared in 2010 and introduced '70s power pop, psych rock, and proto-punk elements to the group's sound. My Chemical Romance officially ceased operations in 2013 but reconvened in 2019 for a reunion show in Los Angeles and a short run of performances abroad. In 2022, they released their first song in eight years, the sprawling "Foundations of Decay."
