Microradio Sound Walk consists of multiple transmission stations situated along a loosely defined route starting in City Hall Park and branching out throughout the immediate neighborhood. Listeners proceed through the route in the order of their choosing, as they move farther away from one station and grow closer to the next the signal they receive will fall in and out. This sonic progression maps the spatial qualities of the airwaves and provides a tangible example of their ubiquitousness. Listeners worldwide will also be able to tune in the City Hall Park airwaves on free103point9 Online Radio.
