This work with a duration of 4`33`` was produced using sounds recorded inside an outside of the number 28 streetcar which circulates in Lisbon Portugal. It is a very old streetcar that crosses most of the city and is a tourist attraction.
The sounds were recorded inside the streetcar to capture the passenger noises with omnidirectional microphones and on the outside to capture the motor, rail and break noises using a short shotgun microphone.
All sound were recorded in mono and mixed to stereo. I tried to alter as little as possible the sounds, relying mostly on editing.
The sounds used in the work suffered the following processes, reversing of sound, sampling of small portions, repetition and panning.
