Green Day: 'Know Your Enemy'

"It's a rallying song. It's about liberating yourself from a lot of bullsh*t that you see on TV," says Billie Joe Armstrong of Green Day's comeback single. The pop-punk trio have come a long way since the days of naming their albums after forms of diarrhoea and penning tunes about the art of masturbation. Following on from the political-rock-opera-odyssey that was 2004's Bush-baiting American Idiot, next month's 21st Century Breakdown LP promises to be just as epic.

Opening with what appears to be drummer Tré Cool walloping his kit with a monkey wrench, comeback tracks don't come much more blunt and to the point than this. Featuring plenty of "ah-woah-ah-woah" Billie Joe vocals to get the stadiums swaying and with lyrics so politically simplistic your 12-year-old niece could understand them ("Don't be blinded by the lies", "silence is the enemy") this has 'monster chart hit' oozing out of every bludgeoned guitar chord. A fearsome return which bodes well for angry, mosh-happy teens everywhere.
