Radia Show 481: Variance V – David Merlo for Radio Grenouille (Marseille, France). "Radia" is a group of international stations using new and forgotten ways of making radio. Each week, one station makes a show for all the others. This week: "Variance V is a stereophonic retranscription of the 8 speakers broadcasted sound installation Variance IV. The physical and multicasted space of Variance IV’s sound resonance becomes compacted in an abstract and frontal space. In Variance V sound materials and landscapes superimposed in this way then behave like a superimposition of senses and meanings which interfere on each other until their disappearance in a hanged-time space. Variance IV had been presented within the framework of the collective exhibition Archist International, Cités Hétérotopiques proposed in Marseilles by Art-cade, Grands bains douches de la plaine Gallery from 21st to 26th of april, 2014. This exhibition showed a selection of artists, architects and social players works, intentions and proposal inscribed in the urban space. The Variance IV dispositive had taken his place in this exhibition with the intention to use the sound potential which such an event could reveal in the resonant space of the Art-cade Gallery and then process and re-casted it in the same resonant space, using 8 non-synchro speakers. The processing gesture, which exclusively took place in situ and during the time of the exhibition evokes notions like production, assimilation or relation to space. Other personal and collective musical works had been injected in the dispositive during the process. Variance IV is a sound installation dispositive elaborated and performed by David Merlo. Scenography: Rémy Rivoire. Sound control room: Virgile Abela. General control room: Thomas Royez.
