‘Alter Bahnhof’ is created by Janet Cardiff and Georges Bures Miller for the 13th edition of DOCUMENTA. Viewers are given an ipod and headphones and asked to follow the artist’s narrated guidance in pre-recorded ‘video walk’ through the old train station in Kassel. By moving around the viewer finds himself at the locations where the stories in the video happen as he experiences the blurred line between reality of the physical space and cinematic fiction recorded on the video.

“DOCUMENTA (13) takes a spatial or, rather, ‘locational’ turn, highlighting the significance of a physical space, but at the same time aiming for dislocation and for the creation of different and partial perspectives – an exploration of micro-histories on varying scales that link the local history and reality of a space with the world, and worldly.” Carolyn Christov – Bakargiev
it is what it is 
Very interesting.
