By using records, cassettes, and a radio transmitter to perform live sound collages, Kristen Roos pays homage to the history of the phonograph, tape and radio as tools for the development of experimental sound art. His alternative use of commercial media is also a Situationist technique—detournement, in which a familiar medium is re-purposed to create something new.
The Micro Radio project started as a site-specific sound and radio project in 2005. It involved collecting site specific sounds, creating compositions, and broadcasting them back to the collection site. Roos stored the sounds on his laptop and broadcast using a low-power radio transmitter (capable of transmitting 150 feet).
In 2006, Roos began experimenting with a radio transmitter and antenna capable of broadcasting one kilometer. Audio can be downloaded from his broadcasts page.
