New York-based darlings of the European concept performance scene, the Nature Theater of Oklahoma use material gathered from volunteers during the first two weeks of the Foreign Affairs festival to collage together the “college years” episode of Kristin Worrall’s telephone conversation version of her life. The entire conversation is also available in marathon (July 7-12, 14:00) and episodic (July 3-5, 20:00) form. For more information on the FA programme, including the other festival focusses of William Forsythe and the theme of speculation, visit www.berliner-festspiele.de.
