Pierre Jansen was a French composer working in film. He was in particular the permanent collaborator of Claude Chabrol for whom he composed the music for many films.
He also scored the above documentary Acera, or the Witches’ Dance (1972) by Jean Painlevé.

This happened five years ago.
Shusei Nagaoka was a Japanese illustrator. He was known for his music album cover art in the 1970s and 1980s.
He designed album covers for Electric Light Orchestra, Earth, Wind & Fire, Deep Purple, Space, Maze, George Clinton, Kitaro and Rose Royce.
