Joost Klein grew up in Britsum in the Dutch province of Friesland. As a child he takes some hard hits from life itself but he stays afloat by listening to hardstyle and hip-hop, and by starting a career as a Youtuber, calling himself Eenhoornjoost. Of course he starts rapping too, about his life and that of the others and about the world and so on. Joost immediately scores big with Zelfgemaakt and Dakloos and Scandinavian Boy, and with his pal Donnie he delivers an album called M van Marketing for the influential Top Notch label. He relentlessly releases music on his own too; no less than two albums in 2019, Albino and 1983. Bounce along with Joost on Saturday, because one track is even crazier than another!
