Roles DJ · producer · vocalist · promoter · record label founder

Glasgow-born DJ and producer Hayley Zalassi emerged from the city’s club culture, particularly The Arches, where she worked behind the bar before becoming a performer herself. She studied electronic music production at Riverside Music College and developed a house sound that draws on soulful vocals, driving rhythms and euphoric dancefloor records. Her 2021 booking at FLY Open Air was an early breakthrough; she subsequently performed at venues including Sub Club, La Cheetah, The Berkeley Suite and Sneaky Pete’s, and at festivals including TRNSMT, Otherlands and Riverside Festival. She collaborated with Big Miz on Strange Faces, which features her vocals, and released music through Shall Not Fade, Belters 4U and her own Sassy Traxx imprint. She also established the Get Sassy club-night brand in 2024. Her performances have extended to Boiler Room, HÖR Berlin, The Warehouse Project and Ibiza venues. Originally based in Glasgow, she reported moving to Manchester in a later interview.
