In a new interview with Rolling Stone, Green Day frontman Billie Joe Armstrong said the band is moving away from the massive sound on "American Idiot" and "21st Century Breakdown" and going towards a leaner, meaner rock.
He said: "The last two records were studio albums. This one, we started rehearsing every day, constructing these songs together. It felt like we were all in a room jamming, everyone in the mix, throwing out ideas. If you listen to it, it feels grand. But it also feels like a garage band."
"My son asked me, 'Dad, would you ever go back to playing songs like from Dookie or Kerplunk?' I love those records. I love the punk stuff I grew up on. But there are so many bands who make the mistake, 'We're going back, old-school.' Well ... you already did it. So we're changing the guitar sound. We're not going with the big Marshall-amp thing. We wanted something punchier, more power-pop. Somewhere between AC/DC and the early Beatles."
