Performing one-on-one with the viewer, or for a strictly limited number of participants. Performance outside the institution — in a forest, sandy quarry, in the kitchen or veranda. Free from the institutional context, the performance environment interacts with the act itself. As a rule, for the artist the spectator is a replaceable but necessary part of the equation, whereas in a private situation they are unique, not one of many. The exchange between the artist, the spectator and the environment takes place on very different terms.
