Five years after "American Idiot" took Green Day to new heights of superstardom, the group is nearly finished with its next album, "21st Century Breakdown."

Qccording to Billboard magazine, The Butch Vig-produced "21st Century Breakdown" is split into three acts: "Heroes and Cons," "Charlatans & Saints" and "Horseshoes & Handgrenades." While not as overtly political as "American Idiot," the material sampled by Billboard is chock full of social commentary about religion, war and love.

The album blasts off with its title track, an ultra-melodic midtempo rocker with Green Day's familiar three-chord verses and Billie Joe Armstrong's summation of society: "My generation is zero / I'd never make it as a working class hero."

The song then moves it way through a Who-style breakdown with sustained guitar blasts and thumping drums, before settling on a slower, classic rock-inspired outtro.

The next song, "Know Your Enemy" is a similarly sturdy, catchy rock cut demanding "revolution," while "Before the Lobotomy" begins as an acoustic wash before shifting into a heavy three-chord riff and lyrics dripping with antipathy: "I'm not stoned / I'm just f*cked up."
