Radia Show 562: ‘Impure Waves’ by Stefano Giannotti for RadioWORM (Rotterdam, NL). "Radia" is an international group of stations interested in new and forgotten ways of making radio. Each week, one station makes a show for all the others. This week: Amplifier_muzak_1950s Impure Waves is a radio-piece for voice, harmonica, oscillators and mobile phones. It is entirely born during the author’s residency at the Worm Foundation in November 2015. The piece starts with a quotation of the Wikipedia definition of waves read by the author; successively, the text has been smashed by dozens and dozens of Google translations until it has been reduced at the single sentence Plate ten. A Christian family? Words, landscapes, scretches recorded on a mobile phone interact with sounds produced by old modular synthesizers like ARP 2500, ARP 2600 and VCS3. The piece proceeds as a series of abstract sound paintings, based on the idea that life is made of contamination, impure waves which at the end make us all happy (the very last picture proposes a sort of salterello based on a woman laughing). Produced by Dr Klangendum for Worm & Concertzender
