PJ Harvey has become the first person to win the Mercury Prize twice, with her album Let England Shake. The 41-year-old's record was inspired by the horrors of war. She was unable to attend the ceremony in 2001, when she was named the winner the first time round, as she was in the US during the 9/11 terror attacks.
Musician Anna Calvi was nominated for her self-titled album, which was mainly written at her parents' house. It was produced by Rob Ellis, a long-term collaborator of PJ Harvey.
Adele was unable to perform on the night as she was suffering from a sore throat. The Grammy-winning star's record 21 was named the highest selling album so far this year in July by the Official Charts Company.
Nominees King Creosote, aka Kenny Anderson, and Jon Hopkins missed out on the £20,000 prize money. Their collaboration, Diamond Mine, was described as a "romanticised version of a life lived in a Scottish coastal village, marrying simple folk melodies to atmospheric synth washes and stuttering beats".
Elbow's fifth album, Build A Rocket Boys!, saw singer Guy Garvey (second from left) looking back over his life following the success of 2008's The Seldom Seen Kid - another Mercury winner. The band told the BBC they had been "scared by the thought" of becoming the first band to win the Mercury Prize twice.
Katy B wrote and recorded her debut album On A Mission over three years at university. It's a document of late nights, long weekends and romantic liaisons, centred around London's dubstep scene.
Obaro Ejimiwe - aka Ghostpoet - describes his debut album as a "snapshot of my life". Peanut Butter Blues and Melancholy Jam references Kentucky Fried Chicken and Weetabix. His single Survive provoked the strongest response from his fans, he said earlier this year.
Joseph Mount of Metronomy drew the biggest laugh of the night. All the artists were asked to address the audience after they sang on stage. When it came to Mount's turn, he said: "I hope you visit Devon." Their third album, The English Riviera, is a tribute to England's very own Gold Coast, where Mount comes from.
Gwilym Simcock (left) was nominated for Good Days at Schloss Elmau. Tinie Tempah (centre) told reporters beforehand he thought he had a good chance of winning with his debut record Disc-Overy. James Blake (right), a classically trained pianist, received his nod for his self-titled debut record.
Everything Everything describe their sound as "unconventional pop", adding: "It's not really radio-friendly." Their record Man Alive reached number 17 in the UK singles charts.
