JeanJass

JeanJass, a Brussels rapper and beatmaker, initially established himself alongside Caballero as part of a duo that made a lasting impact on the French-speaking scene. A producer known for his crisp loops and thick basslines, he has crafted a signature that is both precise and direct, combining clear punchlines, a taste for irony and a strong sense of rhythm. From Grünt 71 to his first solo performance at the Grünt Festival, his appearances have introduced a more personal dynamic, alternating between bangers and moments of introspection.

On 12 November 2026 he takes the stage at L’Olympia in Paris for an event that underlines his shift to solo work. On the bill: recent tracks, a few classics from the duo and possibly unreleased material, all conceived for a venue where diction and production textures are brought to the fore. JeanJass moves forward with purpose, true to the combination of technique, authenticity and efficiency that has shaped his identity, from the booth to the live stage.
