The album is the trio’s follow up to 2011 debut Tape One and was picked from a shortlist featuring the likes of Biffy Clyro, Mogwai and Edwyn Collins.
Tape Two was picked by a panel of music experts and unveiled as the winner at a ceremony at Glasgow Barrowlands last night (19 June).
Young Fathers received £20,000 for their SAY win while all runners up were given £1,000.
Stewart Henderson, chair of the Scottish Music Industry Association (SMIA), said: ‘On behalf of the SMIA I’d just like to say how delighted we are for Young Fathers. Tape Two is an extraordinary album and a deserving winner out of a phenomenally strong shortlist.
‘The SMIA is extremely proud to be so closely linked with The SAY Award – a prestigious and increasingly important celebration of Scotland’s quite exceptional musical output.’
