Who said punk is dead? Not the two green mohicans bouncing to the sound of Blink 182. The hottest group in skate punk open with a barrage of obscenities set to a fuzz-guitar assault that lasts just 30 seconds, and their fans fling themselves into a maelstrom of bodies. It's like a bouncy castle for grown-ups. The tight set that follows is full of short, cheerful bursts of energy. Imagine Nirvana jamming with the Undertones at an under-18s disco, and you're halfway there.

"What's up, United Kingdom?" asks bassist Mark "Fish Guts" Hoppus. "I remember a couple of hundred years ago you started a war with us which was fucked," adds guitarist Tom "Hot Pants" DeLonge, in a futile attempt to wind up the audience . But this fresh-faced threesome are more naughty than nasty. "I'm gonna have sex tonight," announces Fish Guts, who's taken his shirt off, perhaps in anticipation.

Blink 182, whose album Enema of the State has already gone platinum in America, are young, dumb and full of three-minute come, but when they get the punk power-pop thing right, as on Dumpweed, where the chiming guitars of the verse give way to a double-speed pile-up of a chorus, they're impressive.

The only downside is a lack of the kind of memorable hooks that characterise forthcoming single What's My Age Again? With its powerchord chorus, instant melody, and tales of dating failure, this is already all over Radio 1 and shaping up for a chart entry.

It's more than 20 years since the Sex Pistols burst onto the scene, and we don't shock so easily these days. Punk now seems more amusing than threatening. Blink 182 understand this, play it for laughs, and as a result are a hell of a lot funnier than most comedians.
