An action for house lights performed by Alice Guareschi on a single occasion, for a select audience, at the Olympia Music Hall, the legendary Parisian venue, on April 12th, 2012. The 16 photographs of the series were shot the same day, right after the live activation of the light choreography in the empty auditorium, involving all thirteen coloured lighting channels permanently integrated into the architecture. With a fixed, similar but not identical framing and following the original lighting score composed by the artist, they present a sequence of different movements of lights. By breaking the duration of the action into photograms that can be viewed separately or all together, the spatial arrangement of the work makes it possible to embrace the overall idea at a glance. Made on the occasion of the exhibition at the MAN, Museo d'Arte Provincia di Nuoro (14 July to 17 September 2023); project promoted by the Directorate-General for Contemporary Creativity of the Italian Ministry of Culture under PAC2021.
