Sound Barrier, by Maia Urstad, is a sound installation of some 130 CD-and cassette radios assembled as a wall. They remind us of historical remains of buildings –except that the stones are made of electronics– and reflect issues related to the technical development and our culture of consumption.

The CD players in the wall are playback units for a composition of electronically treated sounds borrowed from radio waves, Morse code, FM- and satellite radio etc. Sound signals that also will be obsolete and forgotten sooner than we might expect.

The sound barrier installation can be seen from Nov. 27 till Jan 23. 2005 at the Electrohype Biennial in Sweden.
