The artist association "ARC Kënschtlerkrees" celebrated its 60th anniversary in 2020, but was unable to organise any festivities due to the pandemic.

The anniversary exhibition "waasserFest" ("waterProof") now marks ARC's comeback to the expo space H20 in Differdange. The association managed to double its members over the past four years, and 45 of them were allowed to contribute one, two, or three pieces to the exhibition.

One of them is Ingo Schandeler, who is renowned for painting over religious canvases. His contribution to the anniversary exhibition was inspired by Banksy's "Season's Greetings", and addresses the issue of water pollution. The pandemic also has a notable presence among the themes represented in the exhibition.
