The Magnetist
Erik Sandberg, 2013
Micke, also known as The Magnetist, is a Swedish cassette tape enthusiast and archaeologist who spends his spare time making monthly mixes, blogging, hosting tape-only club nights and creating sound experiments by demagnetizing cassette tapes.
It has been argued if this is real or just a mockumentary. There is no evidence that the blog of The Magnetist ever have existed and the Web Archive only has one entry of the blog, which contains no posts. According to a user in the Vimeo comment thread the blog was registered by Erik Sandberg, the director of this documentary.
Nevertheless it’s a great documentary with beautiful cinematography and definitely worth your time.
