It’s been quite a summer for massive installation art in New York. Paul McCarthy’s epically filthy WS closed a few weeks ago, but if you’re quick you can still catch Thomas Hirschhorn’s Gramsci Monument, the fourth and final in a series of tributes to great thinkers. Take the 2 or 5 trains beyond the familiar confines of Manhattan’s white wall gallery zone, and in the middle of the Forest Houses, just off Prospect Avenue in the Bronx, you’ll find an inspiring, expansive interactive tribute to Antonio Gramsci, the Italian philosopher and Marxist, one of the most brilliant minds of the 20^th century.
