The award ceremony was held at Glasgow's legendary Barrowland Ballroom.
The winning album, Thirteen Lost & Found, was produced by Franz Ferdinand's Alex Kapranos and was chosen by judges from a short list of 10 albums.
As well as the award itself, handed over by radio presenters Janice Forsyth and VIc Galloway, the winner received a £20,000 cash prize.
''This award means I'll be able to tour again, make a new record...and hopefully pay off some debts. And I'll be able to pay the collaborators on the album.''
The short list was whittled down from the original 20 nominated albums and included The Twilight Sad's 'No One Can Ever Know', the winner of the public vote.
Performers on the night included last year's winners of the inaugural award, Aidan Moffat and BIll Wells, and Edinburgh hip-hop act Young Fathers.
Speaking on behalf of the judges, John Williamson said the decision had been extremely close. "RM Hubbert's album was the one that encapsulated and engaged the most," he said.
