Janne01 has 4 Warhaus concerts.

Warhaus is the solo moniker and alter ego of Belgian (Ghent-based) musician, songwriter and singer Maarten Devoldere (born 1988), who is best known as one of the frontmen of Balthazar. Off the back of Balthazar's Thin Walls (2015), the band members decided to take time off and do some exploring on their own. Warhaus is what Devoldere came up with, from 2016 onwards.
