February 2011: I feature Alexander Chen who has created an amazing musical experience from actual current subway line movement. I can watch/listen to it all day, very soothing, something we can't generally say about riding these lines.
Conductor (2011) by Alexander Chen. this clip above on vimeo isn't interactive. If you want to watch this art in real time go to mta.me
Conductor turns the New York subway system into an interactive string instrument. Using the MTA's actual subway schedule, the piece begins in realtime by spawning trains which departed in the last minute, then continues accelerating through a 24 hour loop. The visuals are based on Massimo Vignelli's 1972 diagram.
