BEVERLY HILLS, California -- Now that Green Day are presumably finally done collecting awards for American Idiot, the guys have only one task left as they embark on the album's follow-up: building new trophy cases.

"We went to Ikea," singer Billie Joe Armstrong joked at last week's American Society of Composers, Authors and Publishers Pop Music Awards.

"Yeah, it cost me 50 bucks, but it took me two years to put it together," bassist Mike Dirnt added.

Actually, Green Day have already started working on what a post on their site curiously called "cool projects" (see [article id="1532147"]"Green Day End Their Vacation To Work On Mysterious 'Cool Projects' "[/article]) -- but is likely the band's next release.

"Everything that we do is contributing to something that we're going to put out," Armstrong clarified, sort of. "We don't have a solid idea yet, it's just the beginning, but the beginning ideas that we have are really exciting.

"For us, everything that we do is completely, 100 percent passion- and energy-driven, so however we're going to come out with our next album, just be certain it's going to be an event, not just putting a record out," he continued. "At this point, to put a record out with like 12 songs on it and turn it in sounds a bit boring for us. So we want to definitely make something that is well thought-out and [that] all of our blood is put into."

So far, the group's been recording demos on a daily basis and working through dozens of ideas.

"We've headed back to the same [mentality as American Idiot], and that is what we really gotta do: Erase all the rules and go in and be productive," Dirnt said. "Be creative but be productive. And if [we] got nothing, record something and just enjoy what we do."

Although Green Day are moving on to their next record, they still plan to make a movie based on the American Idiot story line (see [article id="1491274"]"Green Day Considering Movie Version Of American Idiot"[/article]).

"It's definitely unfolding," Armstrong said. "Every single week there's more ideas about doing a film for American Idiot, and it's definitely going to happen."
