The Glasgow-based producer was shortlisted along with nine others, and was honoured with the £20,000 top prize at an awards ceremony in Edinburgh last week.
The remaining shortlisted albums, including Aidan Moffat and RM Hubbert’s Here Lies the Body, Free Love’s Luxury Hits and C Duncan’s Health, each won £1,000.
The awards ceremony featured live shows sets from upcoming Scottish artists LYLO, Heir of the Cursed, Cucina Povera and Man of Moon.
Robert Kilpatrick, general manager of the Scottish Music Industry Association said: ‘A huge congratulations to Auntie Flo for winning 2019’s Scottish Album of the Year Award for the incredible Radio Highlife.
‘This year’s campaign saw 293 eligible albums submitted, the highest number of any SAY Award campaign to date. Not only does this highlight the fact that Scotland’s recorded output is in great health, but it also shows that in spite of being in the age of algorithm-driven playlists, the album as a format still deeply matters to both artists and music fans.’
Alan Morrison, head of music at Creative Scotland, added: ‘Radio Highlife is absolute proof that Scotland’s music travels a two-way street with the rest of the world. Brian d’Souza as brought the sunshine of Africa into the SAY Award and gives us a worthy winner. Congratulations to him and to all of the Shortlisted nominees.’
Now in its eighth year, previous winners include Young Fathers’ Cocoa Sugar (2018), Sacred Paws’ Strike A Match (2017) and Anna Meredith’s Varmints (2016).
