The Tactical Sound Garden rewrites the idea of locative media. This project intrigues me since it adds an aural, not visual, layer to the city. Most projects that propose a geospatial web or other virtual superimposition over an urban condition run aground due to the problem of attention. As Walter Benjamin points out, we apprehend architecture—and cities—through a state of distraction. Adding some kind of PDA-style visual interface to the city is a fruitful strategy, but fails to engage with this dominant, distracted way by which we experience cities. On the other hand, thanks to the Walkman and the iPod, millions of individuals are thoroughly accustomed to détourning their urban environment with sound on a daily basis. Mark Shepard's proposal for the Tactical Sound Garden suggests that this is something that urbanists will be able to directly engage.
