Concert· Liege
Janina Greven & Daan van Zelm
I don't have any information about an event associated with these names, so I can't accurately summarize it. "Janina Greven" and "Daan van Zelm" don't correspond to a widely known event I can identify. If you can share more details — such as a flyer, event description, location, or the type of event (concert, lecture, exhibition, etc.) — I'd be happy to write a 1–2 sentence summary for you.
