About the film
Romantic Warriors IV: Krautrock is a trilogy of feature-length documentaries about progressive music written and directed by Adele Schmidt and José Zegarra Holder. RW4 focuses on the progressive rock music from Germany popularly known as Krautrock, although the integration of Krautrock into the progressive rock genre is a purely American notion. In Europe, the conventional wisdom is that Krautrock can be considered at most as the connection between psychedelic rock and progressive rock.
The term "Krautrock" was applied after-the-fact by British journalists, and in fact the German bands share very few similarities.
