JeanJass

JeanJass, a Belgian rapper, beatmaker and producer who emerged within the duo Caballero & JeanJass, has forged a signature where technique meets authenticity. Drawing on old-school influences, modern trap and electronic touches, he shapes finely crafted productions and sharp rhymes capable of shifting from self-mockery to intimacy. A respected producer, he multiplies collaborations across the Francophone scene while asserting a more personal solo writing style, already highlighted during his Grünt 71 and later at the Grünt Festival.

On February 17, 2027, he takes over Le Transbordeur in Villeurbanne for a live show that traces his journey. On stage, JeanJass strings together electronic textures, dense bass and understated melodies, alternating ego trips and confidences, and playing on breaks and rhythmic precision. The set showcases his latest releases while allowing familiar landmarks to surface, with particular care given to sound and dynamics. A moment conceived for those who closely follow Belgian rap as well as for curious listeners ready to enter his world.
