Julia Loktev's video is called Said in Passing and here comes the art bit: "A city's subway system is public space in perpetual motion. A constantly shifting no man's land inhabited by people on the move. Five video projections form one long image showing different women riding the New York subway. Their voices can be heard on headphones across from each projection. The women - some actors, some friends and acquaintances of the artist - present themselves in short announcements. Do we get to know who they are or who they would like to be?"
Interesting idea, perhaps I could convince another gallery to try a Tube version, or even charge people for coming into the Tube to see some "reality art".
