These days, it’s not in Berlin, New York, Paris, or Rome that I see the best large-scale group shows of contemporary artists. Go to Budapest, Warsaw, Istanbul, or Riyadh—cities where people have something to demonstrate, something to say beyond decrying gentrification and the cost of housing—and the mega-show suddenly feels vital again.
