“I’ve been thinking a lot about biennials,” mused the artist Michelle Grabner, seemingly without irony. No kidding—she’s one of three curators of the 2014 Whitney Biennial, which opened to the public on the day of this panel, held at the Armory Show. “Here and Now: Biennials in the Twenty-First Century,” moderated by the curator and scholar Lynne Cooke, assessed not so much the current state of biennials—of which the Whitney’s signature exhibition is a leading example—but rather demonstrated how she and two other panelists have shaken off what some call “biennial fatigue” to reinvent the form and scope of these large-scale, super-hyped exhibitions that take place around the world every two, three, or more years.
