From imdb.com: In 1985, Makoto Tezuka, the son of manga genius Osamu Tezuka, was still a film student with a few experimental shorts to his credit and who was entrusted with the mission to turn an album by Haruo Chikada into a musical film. https://www.imdb.com/title/tt0419821/ The film is basically a collection of music videos telling the story of the rise and fall of the band and their involvement with a shady record label. Found this one while looking through old cult movies and realized nobody had uploaded it anywhere, so here it is.
