Never been a fan of performance art, but it is worth an afternoon at the MOMA. The top floor exhibition has some interesting videos and live art of people slapping each other and being naked.
From the MOMA description:
Abramović, best known for her durational works, has created a new work for this performance retrospective—The Artist Is Present (2010)—that she will perform daily throughout the run of the exhibition, for 77 days and a total of over 700 hours. For her longest solo piece to date, Abramović sits in silence at a table in the Museum’s Donald B. and Catherine C. Marron Atrium during public hours, passively inviting visitors to take the seat across from her for as long as they choose within the timeframe of the Museum’s hours of operation. Although she will not respond, participation by Museum visitors completes the piece and allows them to have a personal experience with the artist and the artwork.
