It's been four long years for Green Day fans, but judging by the first single from the new album "21st Century Breakdown", the wait was worth it...

The Earls of Eyeliner are back to deliver a brand new single - "Know Your Enemy" — which will premiere April 24 on more than 250 MTV on-air and online outlets worldwide. It's the first new material from the rockers since 2004’s two-time Grammy Award-winning seminal rock opera American Idiot, which helped cement their rock god status, silenced their critics, and introduced the band to a whole new generation of fans. Coupled with a formidable reputation on stage, Green Day are now one of the biggest rock acts in the world.

Check out Green Day rocking out, catching fire and wearing what director Mathew Cullen described as "timeless" Mod-inspired get-ups when Green Day's "Know Your Enemy" video premieres April 24 at 5.30pm on MTV, and MTV.com.au!
