Originally from Paris, Kalsx spent his youth learning violin and music theory in a conservatoire. In fond of science and artificial intelligence, he soon discovers a new interest for electronic music, which he appreciates both the abstract aspect and the countless possibilities it offers.

As time goes by, he is progressively driven by a strong desire to create and starts writing his first compositions at the age of 22. Inspired by several movements derived from techno music and his classical background, Kalsx develops a deep and eminently melodic style with pronounced psychological patterns. His music is the result of a work of introspection, between dreams and illusions.
