Uncommon Deities appears to be a reconstruction of an audiovisual installation by David Sylvian at the 2011 Punkt Festival at the Sorlandets Kunstmuseum in Kristiansand, Norway. For the cd, Sylvian's poems are read against settings by Jan Bang and Erik Honoré, Arve Henriksen and Sidsel Endreson.
As all of this is alternative and for sale, the David Sylvian website has lots on information. The piece that led me to this is The God of Small Caresses, of which one can hear an excerpt if you click on the image above.
Otherwise, here is a rather beautiful video introduction to the cd with The God of Single Cell Organisms.
