Pape Subway Station (9:32) According to the maker of this video: "This soundwalk is a result of my getting visually lost in the Toronto Transit Commission's "Pape" subway station. That wasn't the intention originally: it was supposed to indicate my difficulty in the subterranean spaces because of my visual limitations. I accidentally zoomed in after a couple of minutes of shooting, so the visual is not very indicative of what I see. The soundscape, though, is fascinating. Source: You Tube.
Note: As the videographer notes his camera zoomed in causing the resulting imagery to be quite random - which is someways facilitates the maker's goal. The environmental sound is interesting and might be best listened to with headphones.
