Part of the appeal of live art is the chance that it could go wrong. There is also a perverse pleasure in observing the authenticity of a mistake in a contrived setting — for instance, actors “corpsing” can prove exhilarating in small doses. The trend of confessional art (and one may extend the point to reality television) offers similar authenticity within an artificial environment, if not to the same extent as an onstage mistake. As playwright and actor Tim Crouch puts it, “To see someone fail and to be embarrassed is a very real thing, and we like it real and unmediated.”
