Radiohead's In Rainbows and Led Zeppelin singer Robert Plant's collaboration with Alison Krauss, Raising Sand, are among 12 albums nominated for Britain's Mercury Prize.

A short list of 12 artists was announced Tuesday for the annual award for the best British album of the year.

Alex Turner of the rock group Arctic Monkeys earned a nomination for The Age of Understatement, an album by his side project The Last Shadow Puppets.

It's a third nomination for Turner — the Arctic Monkeys' first album won the award in 2006, and their followup made the shortlist in 2007.

The Last Shadow Puppets also features Miles Kane of The Rascals.

Other nominees:

• Jazz singer Adele, 19.
• Indie rock band British Sea Power, Do You Like Rock Music?
• Dubstep artist Burial, Untrue.
• Alt-rock band Elbow, The Seldom Seen Kid.
• R&B singer Estelle, Shine.
• Singer-songwriter Laura Marling, Alas I Cannot Swim.
• Electro-pop group Neon Neon, which is a side project of Super Furry Animals frontman Gruff Rhys, Stainless Style.
• Jazz group Portico Quartet, Knee-Deep In The North Sea.
• All-girl folk group Rachel Unthank & The Winterset, The Bairns.

Radiohead's In Rainbows was not eligible for the Brit Awards, the U.K.'s largest music industry awards, because it was released on the internet and sales were not recorded on U.K. charts.

Plant has been touring with bluegrass singer Krauss in support of Raising Sand.

The album is a departure for Plant from the sound of Led Zeppelin. Plant has dismissed rumours of a reunion tour for the legendary British group throughout the tour.

Previous winners of the Mercury Prize include the Klaxons, Arctic Monkeys, Antony and the Johnsons and Franz Ferdinand.

The winner will be announced Sept. 4.
