Performance Art

Performance art is art in which the actions of an individual or a group at a particular place and in a particular time constitute the work. It can happen anywhere, at any time, or for any length of time. Performance art can be any situation that involves four basic elements: time, space, the performer's body and a relationship between performer and audience. It is opposed to painting or sculpture, for example, where an object constitutes the work. Of course the lines are often blurred. For instance, the work of Survival Research Laboratories is considered by most to be "performance art", yet the performers are actually machines.
Although performance art could be said to include relatively mainstream activities such as theater, dance, music, and circus-related things like fire breathing, juggling, and gymnastics, these are normally instead known as the performing arts. Performance art is a term usually reserved to refer to a kind of usually avant-garde or conceptual art which grew out of the visual arts.
Performance art, as the term is usually understood, began to be identified in the 1960s with the work of artists such as Yves Klein, Vito Acconci, Hermann Nitsch, Chris Burden, Carolee Schneemann, Yoko Ono, Joseph Beuys, Wolf Vostell and Allan Kaprow, who coined the term happenings. In 1970 the British-based pair, Gilbert and George, created the first of their "living sculpture" performances when they painted themselves gold and sang "Underneath The Arches" for extended periods. Alongside pioneering work in video art by Jud Yalkut and others, some performance artists began combining video with other media to create experimental works like those of Chicago's Sandra Binion, who elevated mundane activities like ironing clothes, scrubbing steps, dining and doing laundry into living art. Binion has performed all over the world and is highly regarded as an artist in Europe.
Performance art genres include body art, fluxus, happening, action poetry, and intermedia. Some artists, e.g. the Viennese Actionists and neo-Dadaists, prefer to use the terms live art, "action art", intervention or "manoeuvre" to describe their activities. These activities are also sometimes referred to simply as "actions".
