Here is a cool project that my friend Shawn Micallef is involved with...
[murmur] is a documentary oral history project that records stories and memories told about specific geographic locations. They collect and make accessible people's personal histories and anecdotes about the places in their neighborhoods that are important to them. In each of these locations they install a [murmur] sign with a telephone number on it that folks can call with a mobile phone to listen to that story while standing in that exact spot, and engaging in the physical experience of being right where the story takes place. Some stories suggest that the listener walk around, following a certain path through a place, while others allow a person to wander with both their feet and their gaze.

[murmur] was started in Toronto and is in Vancouver, Montreal, San Jose, and other cities. Walter Benjamin would be excited. Perhaps one day [murmur] will be in Seattle.

I hear of similar projects using cell phones, such as the Bike Bin Project curated by Mike Min.

I'm so lucky to know all these creative people who combine audio with geography. Do you know of other sound in the street projects?
