Histories of new media often attribute its lineage to 'time-based media,' which is in turn a phrase generally used in reference to film, video, and photography. Time Frame, an exhibition at New York's P.S.1 Contemporary Art Center, expands these genres and histories in its presentation of ten artists work. The show brings sculpture and installation art into conversation with film and video, and meditates on numerous temporal contexts, including duration, frequency, meter, rhythm, narrative, nostalgia, memory, and reflection. The artists--Cory Arcangel, Felix Gonzalez-Torres, Nancy Holt, Roni Horn, Paul Pfeiffer, John Pilson, Thiago Rocha Pitta, Robert Smithson, Hiroshi Sugimoto, and Andy Warhol--also hail from different generations. The underlying comment made by this assemblage is one about history and perception. The work of older artists is recontextualized in light of younger artists' work, and many in the group deal with the historical reception and post-historical engagement with various cultural ephemera. It's all more approachable than this heady critique might imply, and locals can approach it through 18 September. - James Petrie
