“Know Your Enemy,” the first single from Green Day’s upcoming eighth studio album, 21^st Century Breakdown, is available now. After teasing fans with a snippet of the track, the full version has finally hit iTunes for the world to hear.

 

21^st Century Breakdown, which will be released by Reprise Records worldwide on May 15^th, is the best-selling trio’s first studio album since 2004’s two-time Grammy Award-winning punk-rock opera American Idiot, which debuted at No. 1 on the Billboard chart, spawned five hit singles, and went on to sell more than 12 million copies worldwide. In a recent feature, Rolling Stone called 21^st Century Breakdown “even more ambitious than American Idiot” and “a record of die-hard punk ideals…tightly scripted, continually ascending classic-rock excitement.”
