M.D. Geist was originally released in Japan by Nippon Columbia and re-released under the Denon label.
The audio system features an 8 speaker JBL system powered by a dedicated custom designed amplifier, unlike most other Citroen cars that feature a Denon audio system.
Commercial digital recording was pioneered in Japan by NHK and Nippon Columbia, also known as Denon, in the 1960s.
In Le coq et la perle, now in the Musée Denon, Chalon-sur-Saône, the bird struts by with a pearl pendant hanging from its beak, the image of self-regard.
