The 'American Idiot' band are currently working on the follow-up to 2009's 21st Century Breakdown.
In the video posted on their official YouTube page, frontman Billie Joe Armstrong says: "It's a new sound and it's f**king with my head."
Producer Rob Cavallo adds that the band are hoping to make a "big, powerful statement" with the new LP.
"It takes balls to do this, each hit of every instrument is actually super important, they add up to one thing," he says. "When you get it done, it's like 'Wow, that's a big powerful statement'."
The group recently described the new album as "voyeuristic", and that it will be the first time they have "sung about f**king".
Green Day have also announced their first gigs of 2012, at festivals in Japan and France in August.
