performance art, multimedia art form originating in the 1970s in which performance is the dominant mode of expression. Perfomance art may incorporate such elements as instrumental or electronic music, song, dance, television, film, sculpture, spoken dialogue, and storytelling. The roots of this art lie in early 20th-century modernist experiments with mixed media, particularly in Dada performances. The direct antecedent of performance art, however, can be found in the happenings of the late 1950s and the 1960s. Among the most obvious differences between the two is that the later movement tends to be much less spontaneous in nature than the earlier and that happenings were almost always created by visual artists, whereas performance artists generally have more varied backgrounds, many in theater, writing, or dance.

Primarily an avant-garde form, performance art is often emotional and topical, frequently dealing with political and personal matters and with issues such as race, class, and feminism. Probably the best-known contemporary American performance artist is Laurie Anderson; others include Nam June Paik (earlier also involved with happenings), Michael Smith, Vito Acconci, Carolee Schneeman, and Martha Wilson. Often classified as performance artists are such monologist-writers Eric Bogosian, Spalding Gray, Karen Finley, Anna Deavere Smith, and John Leguizamo.
