A Mysterious Song on the Internet (2019)
This reminds me of the search for Q Lazzarus.  She and her band are famous (or maybe some would say notorious) for writing the song played during Silence of the Lambs when Buffalo Bill does his infamous "dance" in front of the camera.  For decades, folks couldn't find any information on her and weren't even sure that she was still alive.  Jonathan Demme, the director of Silence of the Lambs happened to be in her cab one night and she played some of her music and he really liked it.  He put it into several of his films. It's someone's dream to be discovered like that - and then to fall almost faster back into obscurity?https://www.stereogum.com/2009727/mysterious-goodbye-horses-...
