"Radia" is an international network of stations, including Wave Farm's WGXC, interested in creative and forgotten ways of making radio. Each week, one station makes a show for the rest of the network. Radia Show 472: UIOR from Radio Corax (Halle, DE). UIOR belongs to the experimental German-Russian Noiseart-scene and mixed a heaven & hell-set for Radio Corax and radia.fm. In the last years UIOR started to work with frequencies beyond our audible range – silent sounds effectively … – UIOR doesn’t work for music-labels anymore but joined different fine art ensembles in St. Petersburg and Tallinn.
