Of interest in my book is the connection of Kraftwerk to Afro-American music as noted in “Planet Rock”.
Jon Savage noted in his piece “Machine Soul: A History Of Techno” (1993) that:
“In 1981, Bambaataa and the Soulsonic Force, together with producer Arthur Baker, paid tribute [to Kraftwerk with] “Planet Rock,” which used the melody from “Trans-Europe Express” over the rhythm from “Numbers.” In the process they created electro and moved rap out of the Sugarhill age.”
Simon Reynolds in Energy Flash (1998) similarly remarked:
“In New York, the German band almost single-handedly sired the electro movement: Afrika Bambaataa and Soulsonic Force’s 1982 smash “Planet Rock” stole its doomy melody from “Trans-Europe Express” and its beatbox rhythm from Kraftwerk’s 1981 track “Numbers.””–Generation Ecstasy (1998) by Simon Reynolds
Apparently, none of Kraftwerk’s material was actually sampled, all was emulated.
