Three London Exhibitions: Artschwager, Tyson, Sidén

London's cultural scene presents three monographic exhibitions: Richard Artschwager at Serpentine Gallery (12/01/02–10/02/02), Keith Tyson at South London Gallery (16/01/02–17/03/02), and Ann-Sofi Sidén at Hayward Gallery (17/01/02–01/04/02). Artschwager, an unclassifiable artist working across painting, design, and sculpture, creates works like 'Table with pink tablecloth' (1964) that blur function and illusion. His 'Blp's' are described as parasitic, useless logos invading social space. Keith Tyson's 'Supercollider' exhibition continues his exploration of scientific determinism and the 'Artmachine', a data-to-plan transformer he used until 1999. Works like 'Field of heaven (the longshot magnet)' (2001) and 'A night in a billion' (2001) depict cosmic and molecular combinations. Ann-Sofi Sidén's documentary project focuses on prostitution along the German-Czech border, particularly in Dubi, ten years after the Velvet Revolution. Her video 'Dubi Morning 7 August 1999' and interviews give voice to sex workers and locals, revealing the area's role in sex tourism and police complicity.
