Koky has been on the Czech scene since 2010, when he released his first song as well as the collaboration with Yzomandias (aka Logic) Nejsi G (mixtape Hráč Roku vol. 1). Since 2016 he is often seen on the Milion+ label, where he produces several compositions and continues to work to this day. As of 2018, he is officially a member of Milion+ Entertainment. Koky, despite his label mates and the general trend in the scene, does not use trap elements much in his compositions and sticks to the boombap style.
