Largo da Carioca in downtown Rio de Janeiro on a hot November afternoon. A disconcerting experiment with one very simple instruction: cross this square blindfolded with the help of an attentive guide and, at the same time, describe one’s immediate sensations and impressions. This means walking as if blind for about 20 minutes and having your impressions recorded. The experiment produces a series of sound recordings featuring the voice of the blind stroller along with the noises from Largo da Carioca in the background. Note the stifling heat and the uneven ground…impressions concerning the cries of hawkers and the noise of traffic…all sorts of remarks that attempt to put into words what is perceived and felt along the way.
