Publisher Note

This record was created as part of the solo exhibition of Petra Köhle and Nicolas Vermot-Petit-Outhenin “Blue skies becoming almost black”. at the gallery Annex 14 in Zurich.
Side A of this record contains a recording of the composer and double bass player Tobias von Glenck and was created as an improvisation during the opening of the exhibition. The point of departure for the improvisation was a score of twelve monochrome blue photographs installed in the exhibition, structured in four overlapping constellations. The monochromes are based on the cyanometer developed by Horace-Bénédict de Saussure in the 18th century, a color scale that quantifies the intensities of the blue sky.
The recording of the improvisation was transcribed after the concert by Rätus Flisch, double bass player and professor at the Zurich University of the Arts. Side B was created as an interpretation of this notation and was played again by Tobias von Glenck and recorded by Adrian Scarpatetti in the same exhibition.
This edition, limited to 32 copies, contains a 10" vinyl record and a monochrome original colour photograph mounted on cardboard in one of 9 selected shades of blue.
