Transparency Actions developed during La Noche en Blanco, Madrid (September 22, 2007)

PUM PUM

People waiting in a queue emit sounds imperceptible to human ears. But these sounds can be made perceptible with the mediation of electronic devices. Small corporal microphones are distributed among those in line; these personal sounds then spread to the public, creating a unique composition. This ongoing generated symphony is played live for the people who have composed it.

Radio Mundo

The queues at La Noche en Blanco contain people from all over the world. The richness of this diversity has been made visible through sound-transparency systems that elaborate the cartographies of all the territories and regions connected to Madrid. The system distributes ten speakers that broadcast radio stations transmitted from the countries of origin of people occupying determined positions in the line.
