Heist

Heist (real name Jim Muir; also credited as James Muir on MusicBrainz) is a London‑based producer and DJ working primarily inside drum and bass and jungle, with output that also embraces liquid funk and ragga‑tinged rollers. His practice spans adjacent bass music styles listed under his profile, including dubstep, drumstep, breakbeat, bassline and bass house.

Public biographical detail is limited, but verifiable points trace a long career in the UK scene: Heist has released across a range of drum and bass labels and runs three imprints — Sumo Beatz, Co‑Lab and Calypso — which he uses to put out his productions and collaborative projects. He has worked as a sound engineer and collaborator with Goldie, including work connected to Rufige Kru‑related projects, and he has performed as a DJ and producer across the UK and internationally over many years.

Musically Heist operates across a wide bass spectrum. His recorded work and DJ sets move between club‑focused low‑end and breakbeat complexity: tracks lean on tight, edited breaks and pronounced sub‑bass lines when they head towards drum and bass/jungle, and use cleaner four‑to‑the‑floor bassline or house‑derived low‑end when they cross into bassline, bass house or funky house territory. Where liquid funk elements appear, he favours sustained pads and vocal fragments to open space for bass movement; on the rougher side he incorporates ragga phrasing and chopped-up break edits. Across those modes he shows a practical studio approach — engineered arrangements that prioritise transient clarity on snares and body in the low frequencies — consistent with his background as a sound engineer.

Heist’s role in the scene is both technical and curatorial. As a label operator (Sumo Beatz, Co‑Lab, Calypso) he programmes releases and collaborations; as a studio engineer he has contributed technical skills to sessions with Goldie and Rufige Kru‑linked work; and as a DJ he presents sets that traverse jungle rollers, liquid selections and heavier bass cuts, bringing his production choices into the booth. Public records confirm his continued activity as a performer and release‑maker rather than a single‑release artist.

Directly traceable influences and connections include his engineering and collaborative relationship with Goldie and involvement in Rufige Kru‑related projects; beyond that, public sources offer only limited additional detail under the name Jim Muir / James Muir. Heist remains active running Sumo Beatz, Co‑Lab and Calypso while producing and DJing across drum and bass, jungle and neighbouring bass genres.
