The theme of next year's Sao Paulo Biennial is Iconografias Metropolitanas (Metropolitan Iconographies) and, against a background of global uncertainty, it is appropriate that Ireland's representative will be film and photographic artist Clare Langan, writes Aidan Dunne. Her work, Too Dark For Night is an intense, haunting, hallucinatory journey into a post-apocalyptic landscape in which a city, perhaps, Ozymandias-like, a civilisation, has been engulfed by desert. Langan's work is visually inventive: she custom-builds a variety of camera lens filters and disorientates us with skewed optics. This film, the second in a projected trilogy (the first was Forty Below) exploring the underlying fragility of the human hold on the planet, was shot on location in the Namib Desert.

The biennial takes place from March 23rd to June 2nd next year.
