“Systems of Belief,” a group show that dives deep into artistic worldbuilding, opens at HALLE FÜR KUNST Steiermark in Graz, Austria. Intriguingly, it puts works by late artists like Storm de Hirsch, Paul Laffoley, and Lee Scratch Perry in conversation with young(er) artists including Irina Lotarevich and Harm van den Dorpel. The latter contributes Markov’s Dream (2022, image), a generative NFT subdivision study (based on a 2004 work) inspired by the Russian mathematician.
