Radia, the international group of independent cultural radio stations, presents a new show realised by one of its members, exploring new and forgotten ways of making radio. Today: show 645. A journey through the sounds and words of Suden Radio - a special edit of the live transmission Radio Papesse presented at Savvy Funk as a carte blanche for Saout Africas. Featuring fragments of works by Andrius Arutiunian, Valentina Bonizzi, Charo Calvo, Abdellah M. Hassak, Alyssa Moxley, Bartosz Panek, Polisonum and Pablo Sanz. Visit radia.fm for more information.

A double bill of Mobile Radio's overview of independent and not-for-profit community, 'free', campus, and other radio stations which provide a wealth of material and perspectives outside of the mainstream media orthodoxy. This series constitutes a major retrospective of the work of the radio art network Radia, whose collective mission is to make radio that transcends the borders and boundaries of land and language. Mobile Radio visits each station in turn to discern their motives and inspirations, and explore the work of one of their associated artists. In this episode they speak to DinahBird, Nicolas Horber and Julia Drouhin of Radio Campus in Paris, France. Radiaphiles is part of a commission for documenta 14, and will be aired in Kassel and Berlin from 17 June to 7 July 2017. For more information visit mobile-radio.net.
