Alexandre Estrela (1977) through his work, mostly audiovisual, investigates the essence of images and evokes experiences, leading the spectator to the elaboration of different conceptual meanings, questioning the elements that constitute the moment of apprehension and the relation between the images and those who observe them. The pair of artists João Maria Gusmão & Pedro Paiva explore, through analogic experimental film, photography and installation, paradoxical processes and the convocation of the unconscious, making use of the absurd and the creation and suggestion of improbable situations.

- Lua Cão
, an immersive exhibition of moving images, the result of a partnership between Alexandre Estrela and João Maria Gusmão & Pedro Paiva, was initially presented by the Zé dos Bois Gallery, in the Azores and in Lisbon, in 2017. A group of twenty-one films, videos and images that, following a technical script of four hours, followed by a film technician, changed every fifteen minutes. The exhibition was also shown in Munich and Madrid, at the Casa Encendida, both in 2018, organized by Natxo Checa, as before. However, it is during the exhibition at Kunstverein, in the city of Munich, Germany, that appears the publication that originates this series of ten collages. This special edition is the result of the meeting of the nature of the artists's work, in the role that the mechanics of vision play in both artistic practices and by the common interest in moving images that consistently connect abstractions and illusions. It formally results from the fusion and superposition of still images from the videos and analogic films shown at the exhibition, the symbiosis of these new hybrid images giving place to different interpretations and allowing other gazes, causing the continuous reverberation of this group project. The title - Lua Cão
refers to a rare optical phenomenon caused by the refraction of moonlight in ice crystals, forming a tenuous circle around the moon.
