Parody of late 1979/80/81 German Punk and New Wave groups, all done by Xao Seffcheque and group, plus some guests.
German music papers of the time took it seriously as a state-of-the art compilation, and the real Kraftwerk took legal action and forced stickers (and later on printed on the back itself) claiming parody status. A7 is made up from real Mittagspause tapes, A9 is really by Sternhagel (who features in Seffcheques group of musicians). Side 2 has a locked groove.
Cover and Side 2 (between DAF and KFC) has a track listed as "Residenz - Alles", duration 0:00, so nothing there.....
