"Radia" Show 544: "Sentient" by OttoannA from Radio Campus in Paris, France. "Radia" is an international group of stations including Wave Farm Radio and WGXC interested in new and forgotten ways of making radio. Each week, one station makes a show for all the others. This week: "This is a composite piece from various past and current works by OttoannA which mixes field recordings with ​acousmatic composition​, multilayered collages, fragmented narration,electronic and electroacoustic synthesis… . A sonic trip through ethereal mindscapes that intertwines the tale of Marko Stepanov, an artist and outsider, whose life was transformed by a​ lightning strike whilst on a solitary mountain hike. ​OttoannA Formed in Paris in 2004, OttoannA (Rodolphe Alexis and Valérie Vivancos) have been producing sound pieces, devices, publications and participative actions. Their passion for processes has taken various shapes including a software that singles out fragments from TV news and rearranges them into a poetic litany, memories of familiar routes recorded on the edge of hypnosis, one-to-one DJ sets, transposing sounds from the streets of Paris to those of New York via boomboxes, a barely audible live set performed from inside a closet, and audio voyages by boat and in planetariums.
