Explaining "Happenings"

Allan Kaprow's 1961 essay about "Happenings" in New York provides the reader with an explanation of the phenomenon that swept the underground art scene during the early sixties. A Happenings, as Kaprow describes them "Are events that, put simply, happen." 

To be slightly more specific, Kaprow was referring to somewhat impromptu art performances that people would put together in spaces that were not typically associated with theatre; lofts, vacant stores, parks, etc. 

Kaprow explained some of the differences between theatre and Happenings, which included much less adherence to traditional theatre methods, as well as a lack of a stage, and an increased interaction with the audience.

Based on Kaprow's essay, I kept thinking of the example of Fuerzabruta, the South American "performance art" that is currently housed in a former bank in Union Square, as an example of what he would consider a Happening.
