Young Fathers have won this year's Mercury Prize for their album Dead.
The Edinburgh-based act were little fancied for the award and beat acts like hot favourite FKA Twigs and Damon Albarn to the £20,000 prize.
Band members Alloysious Massaquoi, 'G' Hastings and Kayus Bankole took the coveted award during a ceremony at the Roundhouse in Camden, north London.
They also beat south London poet Kate Tempest and Hammersmith funk duo Jungle to the title.
In a brief acceptance speech, the Massaquoi said simply: "Thank you, we love you, we love you all."
The group had been just 14-1 to collect the prize at a ceremony hosted by Radio 1 DJ Nick Grimshaw.
The judges described their album as; "a startlingly original take on hip-hop. Brimming with ideas, a potent mix of pop, rap, rhymes and rhythms. Ominous and exciting."
The group have shifted only a handful of copies of their album with just 2,386 sold by this week - just a sixty-fifth of the quantity sold by fellow nominees Royal Blood.
Even following their inclusion on the shortlist, they managed to sell only an extra 531 copies of their album - a 31 per cent rise.
Simon Frith, who chaired the judging panel, said of the winners: "Young Fathers have a unique take on urban British music, brimming with ideas - forceful, unexpected and moving."
At a press conference after their win, the taciturn trio had to be asked to smile by photographers and still continued to look stony-faced.
Massaquoi - who is joined in the band by Kayus Bankole and G Hastings - said: "We go out and do what we do."
The act, formed in 2008, have clocked up appearances at numerous festivals and have been described as a "psychedelic hip hop boy band".
They follow in the footsteps of recent winners such as James Blake and Alt-J, as well as other past victors such as Pulp, Arctic Monkeys and Franz Ferdinand.
