Lum is Liam Sanagan, the above is a video for his track I Am Alone. He’s also part of First Rate People (who we previously featured on Weekend Tunage). Turns out his solo stuff is just as good, rnb styled pop with layered vocals ahoy.
I also can’t stop listening to his track Really Difficult, which sees his vocals layered over an Uffie sample. His most recent demos are available to download here.
