Since 2020, DECO 5000 has released a steady stream of impactful singles and EPs across platforms like Groove Estate Records, Mhost Likely Black, and Underzone. In 2025, the project debuted on COMMA.records with Decosystema Vol. 1 — a five-track collection that blends high-octane originals with remixes from label collaborators, solidifying DECO 5000’s presence in the COMMA. roster.

Live, DECO 5000 has earned a reputation for high-intensity, emotionally resonant DJ sets — from rooftop and Mainstage performances at Musikkfest Oslo for Streetbackboys and support slots for artists like Function. Every set is designed to test boundaries between nostalgia and forward motion.
