Demilich is a Finnish death metal band, which formed in the early 1990s and consists of vocalist/guitarist Antti Boman, guitarist Aki Hytönen, bassist Ville Koistinen, and drummer Mikko Virnes.

Nespithe was featured in Terrorizer's Secret History of Death Metal, in their list of "The 40 Albums You Must Hear"; they commented: "Even trying to scream your lungs out whilst vomiting a mix of haggis, outdated goat's cheese and kebab won't do.

Tested extensively by Terrorizer's scientific team, we can now safely say that no normal human is capable of reproducing the effect-free vocal madness displayed by Antti Boman on these Finns' sole, totally unique, album.

[2][3] Demilich was founded in 1990 by guitarist/vocalist Antti Boman and drummer Mikko Virnes, creating a unique avant-garde sound of technical death metal in A standard tuning, with extremely low-register vocals.

The only Demilich full-length album Nespithe has been reissued several times over the years in various guises, but always using the inferior 16-bit CD masters and sometimes brickwalled beyond recognition.
