Today we feature Melissa Dubbin and Aaron Davidson's "Last Transmissions." Last transmissions typically occur at times of crisis and cultural importance. These historical chapter markers often register as more significant than all previous transmissions. "Last transmissions" includes sign-off broadcasts from now defunct radio stations, last addresses of public figures, and last radio contacts with ships, planes and satellites. Rebroadcasting this collection of messages creates openings into divergent narratives.

Welcome to "The Radio Art Hour," a show where art is not just on the radio, but is the radio. "The Radio Art Hour" draws from the Wave Farm Broadcast Radio Art Archive, an online resource that aims to identify, coalesce, and celebrate historical and contemporary international radio artworks made by artists around the world, created specifically for terrestrial AM/FM broadcast, whether it be via commercial, public, community, or independent transmission. Come on a journey with us as radio artists explore broadcast radio space through poetic resuscitations and playful celebrations/subversions of the complex relationship between senders and receivers in this hour of radio about radio as an art form. "The Radio Art Hour" features introductions from Philip Grant and Tom Roe, and from Wave Farm Radio Art Fellows Karen Werner and Jess Speer. The Conet Project's recordings of numbers radio stations serve as interstitial sounds. Go to wavefarm.org for more information about "The Radio Art Hour" and Wave Farm's Radio Art Archive.
