The excellence of Christoph Girardet and Matthias Müller?s work, as well as its close ties with the International Short Film Festival of Vila do Conde, is one of the sources of inspiration for this project; it contributed to its creation and has become the starting point of Solar?s programme. Girardet (1966) and Müller (1961) have been creating exemplary work at the frontier between cinema and video art. In 1991 Girardet started his artistic career more in the area of video art. Müller, on the other hand, began his career in 1993 directing experimental films. During the early stages of their work, between 1991 and 1998, both used found footage as the main component of their creative process. Müller used it in his poetic and autobiographical experimental films whereas Girardet used it in a more cerebral fashion, based on repetition and editing. Girardet and Müller have known each other since those days but it was only in 1999, when the MOMA Oxford commissioned some work for the ?Hitchcoock and Contemporary Art? exhibition, that they directed their first collaboration, the film/installation ?Phoenix Tapes?. This work was the initiation of a partnership which has produced a series of joint projects, although they continue to work individually on films and exhibitions. For the last fifteen years their films have been frequently shown at major film festivals around the world such as Cannes, Venice, Berlin, Locarno and Rotterdam. At the same time they are regular participants in more specialised events such as Oberhausen, Vila do Conde and Clermont-Ferrand. Their work has been shown in reputed international museums and art galleries such as MOMA in New York, Tate Modern, London and is part of important public collections such as the Georges Pompidou Centre collection, Paris. The materials used in their video, cinema and photographic work come from different sources, but mostly from found footage which both directors have been collecting for several years and from their own material in Super8, 16mm and video. In the production of their films, video installations and exhibitions, Girardet and Müller show ceaseless determination in revisiting their vast archive, in reusing it and in adding new research. Often their work resembles that of a DJ who, by using fragments of songs by other writers and combining them with new remixed sounds, creates his own personal musical universe and, at the same time, reinvents his creative process. Imagery of Hollywood cinema, numerous anonymous home movies and autobiographical research, arranged in a sublime manner through editing and its articulation with sound, are some of the most remarkable and magical elements of their work. Müller and Girardet, both in their individual and joint work, revisit the memories of cinema, developing a personal aesthetic which is focused on the progressive character of audiovisual media and on a consequent perspective. It is in their most recent work, most of it shown at Solar, that they reach the climax of their creative involvement by questioning our own perspective of cinema through the appropriation of raw materials and of the processes of film directing. Their careers show that they have invented new communicative processes that reveal an effective critical positioning which gives a unique character to their re-visitations. They are also proof of their important contribution to the progressive dynamics of audiovisual media. Revisitations was the first exhibition these two authors have presented in Portugal. The show has been being prepared for four months in close collaboration with the authors so that it could be adapted to the space provided by Solar. Besides choosing a series of individual and joint works which have never been shown in Portugal, the pair has created three new pieces specifically for this event. To complement the exhibition, there was a parallel film cycle which included some of their most important short films offering a unique opportunity to see their most recent productions or to re-visit the beginnings of their careers.
