Keyboard Fantasies: The Beverly Glenn-Copeland Story (2019) on Netflix

Plot summary

In 1986 Beverly Glenn-Copeland was living in near isolation in Huntsville, Ontario, absorbed by science fiction, and self-released a cassette called Keyboard Fantasies: seven tracks that mix folk and electronics, recorded at home on an Atari computer. The record found almost no audience. Three decades on, Glenn Copeland, as he is now known, began getting emails from strangers around the world who had just found the music. A collector of rare records in Japan had put the cassette back into circulation, a reissue followed, and other musicians gave the tracks new plays. In the film he tells that story himself, in interviews and in performance.
