Thergothon was a Finnish funeral doom metal band active from 1990 to 1993. They are one of the pioneers of the funeral doom subgenre. The band only released one demo, Fhtagn nagh Yog-Sothoth (1991), and one album, Stream from the Heavens (1994). Their sound was extremely slow and dirge-like in long pieces, which combined heavy guitar riffs, extremely deep death grunts and sparse lead guitar melodies. They disbanded a year before the release of the album and its members focused on other projects.
