Sub Dub has been played on NTS over 20 times, featured on 20 episodes and was first played on 17 April 2017.

Though no electronic act bested the Orb at creating a satisfying fusion of ambient music and dub, Sub Dub came the closest with its blend of studio production and live instrumentation. The quartet, which includes bassist John Ward, programmer Raz Mesinai, vocalist Ursula Ward, and Grant Stewart on tenor sax, debuted in 1994 with the Babylon Unite EP on TKI. After one more EP, Dawa Zangpo, Sub Dub released their debut album in 1996 on Instinct. Dancehall Malfunction followed in 1997.
