Jonas Grambach, known professionally as yunis, is a Berlin-based producer and DJ from northern Germany. His work sits at the intersection of drumstep, halftime and leftfield bass within the broader drum & bass/jungle orbit. He also operates as a composer and sound designer.

Public records show yunis has released music on labels including Neosignal, Mad Lab Audio, Saturate Records and YUKU. He has toured across Europe and North America and is active on the live circuit as both a producer-performer and a DJ. In 2023 he received a project grant from Musicboard Berlin and is listed as founding his own label in 2023.

Stylistically, yunis’s productions draw on drumstep’s half-time pulse while keeping tempo-range energy associated with DnB. His tracks lean into leftfield bass aesthetics: layered low end, exposed midrange grit and textural sound design. In practice this shows up as prominent sub-bass layering under modulated mid-bass tones, chopped and re-pitched break elements rather than straight four-on-the-floor drums, and the heavy use of space—long-tail reverbs, delays and pad layers—to set contrast around percussive hits.

On the production side yunis applies techniques common to halftime/drumstep and leftfield bass: tight transient shaping on snares and kicks, aggressive low-pass and band-shelf automation on bass elements, and resampling/granular edits to create unusual timbres. His arrangements often alternate dense, bass-forward sections with sparser, atmospheric passages that highlight sound-design details, which is a characteristic approach in his releases and live sets.

Career highlights that are publicly verifiable include the label releases named above, European and North American touring activity, work as a composer and sound designer, the 2023 Musicboard Berlin project grant, and founding his own label in 2023. Those points mark his activity both as a record-releasing producer and as a practitioner of bespoke audio work outside club-facing releases.

There is no widely published, detailed list of personal influences for yunis; public material limits specifics on which artists or scenes he cites directly. What is documented is the stylistic shape of his output — drumstep/halftime frameworks, leftfield bass sound design, and a practice that spans releases, touring and commissioned composition/sound-design work.
