JeanJass

On 26 February 2027, La Belle Électrique in Grenoble hosts JeanJass. A Belgian rapper, beatmaker and producer first known as part of the duo Caballero & JeanJass, he has developed a crisp lyrical voice that balances self-deprecation with a clear-eyed perspective, and a sonic signature that blends old-school, modern trap and electronic textures. As a solo artist he explores a more introspective vein, where command of flows meets personal themes, without sacrificing effective hooks or a keen attention to production detail.

On stage, JeanJass draws from his recent projects as well as the duo’s standout tracks, stringing together self-produced beats, tight verses and meticulously timed transitions. The live show highlights the producer as much as the MC: tempo variations, precise placements and arrangement choices that give the lyrics room to breathe. A set designed for the stage, alternating between bangers and more stripped-back pieces, it traces the continuity between his collaborations and his solo explorations, revealing the breadth of his world without unnecessary effects — just the music and the words.
