ABSTRACT In light of constantly exploding bandwidth and nearly limitless digital storage, FM radio may appear an anachronistic means of communication. However, many new media artists are using this most ephemeral, unindexable, “old” medium instead of or in addition to digital technologies. In this paper, artist Sarah Kanouse discusses three of her own projects that use radio transmission as a unique public material to create ephemeral monuments to difficult moments in American history. By using an analog and dissipating material, these pieces suggest that the struggle to remember is more meaningful than the total recall promised by the digital archive.
