Thergothon was a Finnish doom metal band which lasted from 1990 until 1993 and pioneered the funeral doom subgenre. They only released one demo, Fhtagn nagh Yog-Sothoth, and one album, Stream from the Heavens. 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. The band disbanded a year before the release of the album and its members focused on other projects.
Niko Sirkiä and Jori Sjöroos went on to form This Empty Flow, which marked a distinct stylistic departure from Thergothon. The project began as somewhat of a shoegaze band, taking cues from groups like Slowdive, but ended up as more in the area of trip hop.
Lately Sjöroos has gained reputation for composing songs for popular Finnish pop rock act PMMP.
Sirkiä, later known as Niko Skorpio, works as a visual artist and records experimental electronic music. He also used to run a record label called Some Place Else.
