I've known of Daniel Johnston and Wesley Willis since the early 90s, but I never knew they were in their own genre of music called “outsider music”. I've just spent the last couple hours exploring outsider music. It's the weirdest stuff. It's not good. It's strange. I’m glad it exists. Here is a video explaining the genre. https://www.youtube.com/watch?v=CVks07UgVQQ&t=16s For some reason this stuff intrigues me.
The Beautifully Strange World of Outsider Music

@mace A friend that met Daniel (early 90’s?)told me they exchanged cassette tapes of each other’s music. He learned that each tape Daniel handed out was unique. Rather than record a set of songs once and then copy it (tape-to-tape) as my friend had done with his own music, Daniel would re-perform his music by playing into a boombox sitting on his piano until the tape was filled.
@kerryallen that’s crazy. I never really gave his music much of a listen until today. Once you get past the weirdness and understand it’s unlike most music you’ve ever heard, it’s pretty good.
@mace Check out his Wikipedia page. He was an interesting guy. https://en.wikipedia.org/wiki/Daniel_Johnston?wprov=sfti1
