Similar in tone to the "happenings" of the 1970s, Nitsch's examples of Abstract Expressionism and action painting make Pollock and Warhol look like Grandma Moses. His performances, always for small audiences, involve dozens of actors, musicians, and assistants -- and plenty of offal. The controversy stems from his effusive use of blood and animal carcasses, including lots of disemboweling. Pale, naked models are splashed with red paint, blood, and organs, with some live crucifixion and copulation thrown in for good measure. Oh and it's all accompanied by discordant music played on strings, brass, and kettledrums. Don't miss this viscera-throttling film experience -- but do skip dinner beforehand.
