A hero for the millennials. Joost Klein flirted with teenage fame on YouTube as 'Eenhoornjoost'. He would post zany little videos. Joost eats toothpaste. Joost gets a smiley tattoo. Happy and harmless nonsense, most of which has sadly disappeared from the net. ‘I'm the white Paul de Leeuw’, says he on the subject. Klein discovered that music can be made with language. The vlogging internet phenomenon is the zaniest singing Dutchman since De Jeugd van Tegenwoordig [The Youth of Today]. Joost is all about clever lyrics and tight beats. ‘Scandinavian boy’, ‘Ome Robert’ and ‘Albino’ are sing-along songs from another planet. And his creativity continues to flow. At 22 he's made four albums, appeared at Lowlands and Pukkelpop and written a story for Children's Book Week. Meet the human bumper ball.
