Hailed as the “biggest new rock act in the world” by Rolling Stone, 5SOS is the only band (not vocal group) in history to see its first two full-length studio albums enter the Billboard 200 at No. 1. 5SOS’s self-titled debut album has sold more than three million units worldwide, with 1.5 million albums and more than 4.5 million single tracks sold in the U.S. alone.
