A Note on ticket price from CoreChaos, the promoters:

“Ticket price will be flexible at the box office on a pay-what-you-can basis.
Either 0 Euro OR 8 Euro OR 16 Euro

Why? We want everyone to have access to our concerts. Those who currently can’t afford concerts don’t have to pay anything. But without the solidary financial help and support of those who can afford art, culture & concerts, an event is not possible even with cultural funding. Whatever you can pay – make an informed decision. There’s no shame at all in not being able to afford concert tickets. If you want to support the event prior to the show, we greatly appreciate anyone that buys a supporter ticket in advance.
