Sinful Biz is the creative alias of Gareth Williams, a UK‑based DJ and electronic music producer who channels his trance roots and a fascination with the seven deadly sins into a genre‑straddling sound that blends melodic trance elements with groove‑based techno and hypnotic basslines. Born as a passion project during the lockdown, Sinful Biz fuses powerful hooks, evocative vocals, and driving rhythms to craft dance tracks that draw support from a wide range of DJs across the electronic music spectrum, earning attention on labels like Cubism and VII and releases such as his Under The Influence EP and more recent singles like London. With his work appearing on platforms like Beatport and collaborations including remixes with artists such as John Askew, Sinful Biz continues to build a presence in trance and techno circles through both original productions and dynamic DJ sets at venues and events.
