Installation art pioneers Edward & Nancy Kienholz’s 1985 sculpture ‘The Ozymandias Parade’ is heartfelt and bitter enough to give pause to both post U.S. presidential election gloaters and wound-lickers. Depicting a national leader and his deputy falling from horses and a top ranking general riding an elderly taxpayer’s back, it also reveals the results of a poll taken this fall prior to the installation asking, “Are you happy with your government?’ The answer was ‘no.’ (At Pace Gallery, 510 West 25th Street through Dec 22nd).
