Mae Liewes has 10 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.
