I don't dislike Papir, but there's something fundamentally wrong with that biography, in fact they embrace the very traditional core of Desert/Psychedelic/Post-Rock. And I certainly won't go too far with labeling them Krautrock either.
I don't know what you have against the Stundum LP. Its duration is twice the size of III, so yeah III is more compact. Nevertheless, Stundum is a psych-kraut masterpiece. It's the dynamics that make it so good ..
