The screening area between Rooms 5 and 6 includes two slide projections by American artists. Hotel Palenque 1969, by Robert Smithson is a series of images of an old hotel in Mexico that is undergoing a cycle of simultaneous decay and renovation, with a sound track of the artist’s voice in an accompanying lecture. In Homes for America 1966-67, Dan Graham finds Minimalist forms in the endless banality of suburban housing ‘tracts’. Both artists are moving away from the traditional art object and finding subjects and structures in the real world, while the use of slides exemplifies the interest in serialisation shared by many artists of the period, and their challenge to the aesthetics of photography.
