Robert Wilson's The Life and Times of Joseph Stalin was presented at the Brooklyn Academy of Music on December 14, 15, 21, and 22. This performance was an unusual event. It consisted of seven acts and lasted for twelve hours. Since Stalin began at seven in the evening and ran until seven the following morning, it became a singular event in the life of the spectator, who had to change his habits in order to attend it. Even before it began, the performance had imposed itself on the spectator by the expectation of its unusual length. At least in part, the duration of the piece was an attempt to physiologically modify the perception of the spectator. During the twelve hours, the spectator had to accommodate himself to the slow tempo of the performance; as he became physically tired (sometimes on the verge of sleep), his mode of perception altered.
