As electronic music continues to embrace faster rhythms, TroyBoi and Fabian Mazur are taking a different approach with their new collaborative single, “Shoulder Lean.” Out now via Ultra Records, the track leans into the heavier side of trap, delivering dark atmospheres, deep sub-bass, and a hard-hitting drop built to shake festival sound systems.
Driven by a half-time groove and stripped-back production, “Shoulder Lean” puts the focus on the elements that helped define festival trap: weighty low-end, sharp rhythmic details, and a bounce that hits without needing unnecessary layers. The result is a bass-heavy collaboration that favors impact over speed, bringing a raw, unapologetic sound to the dancefloor.
The production brings together TroyBoi’s signature wonky, syncopated rhythms and Fabian Mazur’s precise sound design. Together, the artists build a track around tension, space, and a punishing drop, creating a sound suited to both mainstage systems and late-night drives.
The release follows TroyBoi’s recent FT EP, also released through Ultra Records. Across its seven tracks, the project explored a broader range of sounds through vocal collaborations with Daya, Morray, and Rockie Fresh. The EP also arrived alongside his intimate North American Hear2Move tour. With “Shoulder Lean,” the producer shifts back toward instrumental-driven trap, putting the emphasis squarely on heavy bass and gritty production.
Rather than chasing current trends, TroyBoi and Fabian Mazur lean into the qualities that have kept trap a fixture in electronic music: powerful low-end, deliberate pacing, and unmistakable rhythmic swing. The collaboration serves as a reminder that a slower drop can carry just as much force when the production gives every sound room to hit.

The track has already received early mainstage support ahead of its official release, with Zedd playing “Shoulder Lean” during Zedd In The Park, signaling its potential to make an impact on festival crowds.
“Shoulder Lean” is available now on Spotify, Apple Music, and other major streaming platforms via Ultra Records.
