Teatr Provisorium presents a pacy dramatic collage, assembled from Goethe's Faust, Dostoyevsky's The Brothers Karamazov, Thomas Mann's Faust, the Book of Job and other texts. It's like a tragic cabaret, illuminating its ghastly subject - the nature of evil - with dazzling and bitter wit. Janusz Oprynski's inventive direction is complemented by Jan Maria Kloczowski's propulsive score which drives the plot. Even the most baleful moments (such as a meditation on the death of Eurydice, taken from the poet Zbigniew Herbert) are performed with lugubrious irony by the Polish two-man cast. In spite of the weight of the subject and the seriousness of its treatment, it is impossible not to leave laughing. Richard Demarco Gallery, 17-21 Blackfriars Street (venue 22), 031-557 0707. 9.30pm. To 5 Sept.
