One of Krautrock big questions was why did CAN ended?
I knew from other sources that the guys in the band didn't want to pay the royalties for the songs written by Rosco Gee on the last two CAN albums.
And the songs written by Rosco are really wonderful and he was a very prolific songwriter in CAN, Rebop composed nothing in CAN and died early at 38 on 12Jan1983. Damo Suzuki left the band soon for the same reason but didn't say anything, stayed silent.
Michael Karoli disclosed it in his own way to E&MM in March1983:
https://www.muzines.co.uk/articles/michael-karoli-on-guitar-improvisation/5919"By the time of the last LP the group had new members who came from a world where a piece is written by one person and the person who has written it gets the credits and the money. Can when it was really Can has always rejected that idea totally. Single characters making their own music was all that was left, and on the last album everybody went their own way, everybody opened up and did things that possibly they wouldn't otherwise have done. I'm just talking about a general feeling, not specific pieces. For instance, on one track I put a short wave radio sound which was later vocoded by the voice — or which later vocoded the voice, whichever you say! — and the whole thing became really personal and all ideas of being commercial were dropped. It was clear by then, Holger having left, that somehow the band didn't exist any more."
