What happens when a group of performance artists go undercover at Tate Modern?  Ordinary activities like standing in a queue, travelling on an escalator or listening to a gallery tour -guide takes on strange new dimensions.  Artists Dora García, Jiří Kovanda, Roman Ondák, Mario Garcia Torres, Nina Jan Beier and Marie Jan Lund explore the way visitors behave in a museum, subtly intervening to disrupt the usual codes of conduct.
