NEW YORK, NY.- The human form, disrobed and displayed in all its glory, is arguably the most enduring motif in the history of Western art. Museums dedicated to art both ancient and modern are filled with nudes rendered every which way: painted, chiseled, molded, sketched and photographed. Theyre just usually not living and breathing. But come March 14, New Yorks Museum of Modern Art will host daily performances of five seminal works by Marina Abramović, three of which feature performers in the altogether. In Imponderabilia (1977), two players stand opposite each other, au naturel, in a narrow doorway.
