Featured Review Great Rivers Biennial A consciousness of art's ability to speak to issues beyond itself pervades this triptych of large-scale installations by the three recipients of this coveted regional honor. In Martin Brief's Amazon God, scrolls depicting what appear to be EKG or seismography charts betray, upon closer inspection, meticulous handwritten lists of books culled from an Amazon.com title search for the word "God." The lists run the gamut of categories, from Religion to Fiction to Food: "God" proves to be ubiquitous, elusive and highly marketable. Sarah Frost's Arsenal is a cascade of firearms, crafted out of white paper, that dangle from transparent strands and look alternately like an onslaught of bones and a static snowfall. The guns were constructed from instructional videos made by children and uploaded onto YouTube, revealing a peculiar community that has an eerily playful (and sophisticated) notion of firearm mechanics. Cameron Fuller's From the Collection of the Institute for the Perpetuation of Imaginal Processes is a world unto itself, a pastiche of modes of museum display and a homage to creativity: A diorama of taxidermied wildlife moves between environmental realism and theatrical camp; vitrines of cardboard masks are interspersed amid a sepia-toned video of a dancing bear, a salon-style display of mid-century photographs of disasters and a bright carnival trailer that imbues the entire work with hints of hucksterism. All three artists have moved beyond physical aesthetics to the realm of social commentary and the use of art to explore and expose cultural sub-currents.
