What is Doomcore Techno?

There is something I always considered highly fascinating about the various Hardcore sub-genres that began in the 90s.
A lot of these genres are virtually unknown to almost everyone. Yet the people involved in these miniature scenes are often willing to dedicate their lives, their free time, their desire, their creativity, their well-being and sanity for their favorite passion. Be it as fans, producers, DJs, promoters, writers...
There is no prospect of fame, their is no inclination to become rich, no respect to be earned by mainstream society, and "groupies" (of any gender) are nowhere to be seen as well - yet these people go on, for years and years, decade and decade.

To use a quote from a British TV show here: "Without hope. Without witness. Without reward".

There are pocket scenes that have a whole history, genealogy, evolution, ecosphere - yet are totally unknown to the outside eye.

And, amongst these, one of the most extreme cases is the genre known as "Doomcore Techno"
The genre existed in "four decades" now. Hundred of producers added their creations to its gene pool. Entire labels and parties committed themselves to the Doomcore sound.
Yet, outside all of this... rarely anyone knows this genre exists, or how it sounds.

It's neither just a "weird categorization" of a style. In music, media, or art, sometimes terms and names are invented to describe a trend or trope, even though the general population could not care less (i.e. who, outside the sphere of journalists and film buffs, can tell "Neon Noir" movies apart from "Neo Noir" movies?).
But that isn't the case here.

Doomcore is an extant and distinct genre, that has many characteristics that sets it apart from other styles like "Industrial Hardcore" or "Dark Techno".

So, to shed some light into this dark corner of the music scene - this book was created!
