Numa cama, numa greve, numa festa, numa revolução: notas sobre materialidades de uma experiência estética

This paper discusses the film A idade da terra (Glauber Rocha, 1980), according to a theoretical-methodological approach that highlights the materiality of picture and sound. There are two gestures here: an analytical gesture, which tries to establish a material contact to the film in question; and the other one, of conceptual tone, which consists in situating the debate on the materiality of communication objects. Through the path of this research for concepts, we have found a fundamental bind between the temporal dimension of forms and the materiality of the aesthetic experience.
