The abbreviation "E.F.S.", appearing in several of the track titles, refers to
Ethnological Forgery Series, a series of songs in which Can "indulged their fascination with
non-Western instruments, scales and rhythms". The song "Doko E" is an excerpt from a
free improvisation recorded at a reunion party in
Schloss Nörvenich with a small invited audience, dated shortly before the first
Future Days recording sessions. The excerpt is taken from half an hour performance, where "
Jaki set up a plodding beat like a donkey bumping along the mountain trails of Provence, as
Damo vented his frustrations with his recent stay" in Japan. The lyrics explore Damo's return to his homeland in Japan, which either wasn't his home any longer, or "that he no longer recognised himself in the mirror of his childhood surroundings". "Doko e" means "where to" in Japanese. "Mother Upduff" is a retelling of an
urban legend involving a family whose grandmother dies while they are on holiday together, and whose corpse—left wrapped up on the roof of the family car—is later stolen along with the car. The recording of tracks "I'm Too Leise" and "LH 702 (Nairobi/München)" are seen in the film
Can Free Concert 1972 by
Peter Przygodda. ==Reception==
