Kraftwerk have a different relation with their record company than most bands. Usually the record company owns the rights to published record, but with Kraftwerk the story is different. Usually there is a copyright(c) sign to the record company and a (p) sign also to the record company. With Kraftwerk all those rights remain with Kraftwerk, at least on the European records there's (p) Kraftwerk, and often (c) Kling Klang. So it seems EMI doesn't do much more than distributing Kraftwerk. I have no idea if this is very worthwhile for EMI. EMI in The Netherlands didn't do any promotion for The Mix for example, as a friend who's in the record business told me. <<<
The same is true for David Bowie (Jones Music, his company), but he and EMI parted ways. BTW, the "P" next to "C" means year of production and which company was responsible for the production. Peace.
