Maarten De Keersmaecker has 4 Joost concerts.

Joost Klein (Born November the 10th 1997, Leeuwarden) did not have an easy childhood. When he was only twelve years old, his father died of cancer. Less than a year later, his mother died of cardiac arrest. He continued as an orphan and started a YouTube channel: EenhoornJoost. It is difficult to put a label on him: he makes absurdist videos without a common thread - in no way comparable to standard child-friendly vloggers. Joost's sketches are often funny.
