Blair Ferguson, 20, won for his contribution to singer-songwriter SZA’s chart number one, Snooze, which was named best R&B Song.
He was also recognised for his contribution to SZA’s SOS album – which won the best progressive R&B category.
The Grammys are the highest awards in the US music industry and are awarded by the Recording Academy of the United States in recognition of musical excellence.
The former Kelvinside Academy pupil began making music in his bedroom aged 15 and adopted the stage name BLK when he launched his career.
After collecting his award, Ferguson told the recording academy: “I feel amazing. It’s incredible to be out here being from Scotland and representing the country.
“It’s not something that happens to people from out there (Scotland) very often.
“It’s incredible, huge thanks to the whole team, to SZA, and to all my co-producers. It’s just been an incredible experience.
“All my family are back home celebrating. They’ve been texting me a lot – I’ve spoken to them a good bit. They’re (my family) all celebrating. It’s been lovely.”
