Green Day recently spoke to Rolling Stone magazine about the upcoming follow up to American Idiot.

Billie Joe added:

I want to dig into who I am and what I'm feeling at this moment – which is middle–aged. We've been doing this for almost twenty years now. You want to make sure you're being honest with yourself. I also have to ask myself, 'What's real out there?'" Right now it seems stagnant.

The band's last album won a myriad of awards and garnered the most critical and commercial acclaim the band had seen since their breakthrough 1994 album, Dookie.
