Here's "Burning Sun"
Burning Sun is a 2000 Green-era song that initially surfaced on riverscuomo.com as a snippet along with a cover of "The End of the World" by Skeeter Davis. This high-quality recording wouldn't reach the public until November 2014, in which a user of 4chan's /mu/ board posted the mp3, claiming that Rivers sent them the file on AIM.
The melody for this song would later be repurposed in "Weekend Woman" on 2017's Pacific Daydream.
