In 2018, J4KIM joined the Estelle Zamme collective as a dancer in a music video. He then collaborated as a singer and co-producer on four tracks of the project.
In 2025, he laid the foundations for his solo project, a condensed blend of sandwiches, darts, and psytrance.
His music is influenced by the French-speaking alternative rap scene as well as more electronic productions, ranging from drum and bass to hard bass, resulting in a unique mix that is rarely represented in Switzerland.
