A usual fashion to hear music nowadays is through headphones. The mp3-player made more music transportable than ever before and public spaces are crowded nowadays with people, living in their own acoustic world. My project is about reversing this situation. I am walking around the city, playing music from an mp3-player, this time not for creating private music, but for diffusing it out of two big yellow hornloudspeakers, radiating the sound to the environment.
