The foremost purpose of performance art has almost always been to challenge the conventions of traditional forms of visual art such as painting and sculpture. When these modes no longer seem to answer artists' needs - when they seem too conservative, or too enmeshed in the traditional art world and too distant from ordinary people - artists have often turned to performance in order to find new audiences and test new ideas.
Performance art borrows styles and ideas from other forms of art, or sometimes from other forms of activity not associated with art, like ritual, or work-like tasks. If cabaret and vaudeville inspired aspects of Dada performance, this reflects Dada's desire to embrace popular art forms and mass cultural modes of address. More recently, performance artists have borrowed from dance, and even sport.
