Sign directing Wave Farm attendees to the Microradio Sound Walk. The Microradio Sound Walk "is a multiple transmitter sound piece and walking tour of local airwaves utilizing broadcast and computer technology to create a soundscape on a single FM frequency that responds to both the architecture and sonic phenomena of a specific space. Consisting of multiple transmission stations situated along a loosely defined walking path, 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 too will shift. This sonic progression maps the spatial qualities of an area's local airwaves. Microradio Sound Walk premiered in 2004 with free103point9 transmission artists Damian Catera, Matt Mikas, Michelle Nagai and Tom Roe." © David LaSpina
