Runkus treats reggae as a foundation rather than a boundary — folding roots, dancehall, hip-hop, soul, bass music and experimental textures into a sound that remains recognizably Jamaican while refusing a fixed genre box.

He began recording at age seven, made a collaborative mixtape with his father as a teenager, and won an RETV talent search while still young. His early band work developed into a solo path that produced Move In (2016), the lockdown-created IN:SIDE (2021), the Toddla T collaboration OUT:SIDE (2022), and the expansive SUPERNOVA (2026).

Across that run, Runkus has worked with and alongside artists including Sean Paul, Tarrus Riley, Toddla T, Jesse Royal, The Skints and Naomi Cowan. His 2026 era also pushed further into visual art through collaboration with Bahamian conceptual artist Tavares Strachan, connecting the music of SUPERNOVA with Strachan's broader art practice.

In August 2026, Runkus headlined Kingston Creative's MoBay Creative Arts Festival, with The Gleaner describing his sound as a blend of reggae, dancehall, hip-hop and experimental music. The publication also noted contributions to projects by Jesse Royal, Protoje and Naomi Cowan.
