They're joined by pal Mark Ronson at NME Awards USA

Klaxons swiped the award for Best International Alternative/Indie Album at the NME Awards USA in Los Angeles tonight (April 23) in the absence of Arctic Monkeys, the real winners.

The Sheffield band earned the award, voted by NME.COM’s US users, for their second record ‘Favourite Worst Nightmare’, but guest presenter, model Agyness Deyn, decided she wanted to give it out to someone on the night.

After she invited Klaxons onto the stage, the band’s Jamie Reynolds, joined by Mark Ronson swiped the trophy.

“It’s a great fucking honour,” Ronson quipped, with Reynolds adding “We’re up for it and we’re having a laugh!”

With Arctic Monkeys singer Alex Turner currently busy with his side project The Last Shadow Puppets, the group were unable to attend the ceremony at the El Rey Theatre.

The other nominees were:

Arcade Fire – ‘Neon Bible’

Babyshambles – ‘Shotter’s Nation’

Klaxons – ‘Myths Of The Near Future’

Radiohead – ‘In Rainbows’

With the British NME Awards already a key event on the global music scene, this year marks the launch of the NME Awards in north America.
