Buscando al pingüino albino

The most outstanding of the veteran artists is conceptual-queen Sturtevant. Her "Push and Shove" room includes all the famous ready-mades -just not by Duchamp. These are unmistakably original Sturtevants. Hollywood bad-boy Kenneth Anger is also worth mentioning, with his shrine-like installation of classic cinema and music moments that is both nostalgic and inspiring.

The show is also full of surprises and hidden artworks. Jonathan Horowitz's 19 portraits of the 9/11 hijackers are scattered all over the museum; a 1991 Basquiat-looking painting supposedly by jazz master Miles Davis looks fake and Dan Colen's plywood board sprayed "Holy Shit" pops up in the staircase.

Down by law is where the Biennial's theme fully acquires meaning. A show within the show curated by The Wrong Gallery, a team headed by Maurizio Cattelan, Down... is a view of America's weirdness through the curious eyes of an outsider. The small room is cluttered floor-to-ceiling with polemic art ( Piss Christ ), artists (Mapplethorpe) and subjects (race, religion, slavery).

Back in the lobby where it all begins or ends, an impressive video projection seems to sum up the spirit of this Biennial. Pierre Huyghe's magnificently absurd A Journey that Wasn't documents an expedition to locate a rare albino penguin. Filmed in Antarctica and Central Park, it is a deceiving film that fails on purpose.
