In Slaughter Natives (alias J. Havukainen) debuted with a self-titled album (Soleilmoon, 1991) in the vein of a sort of avantgarde religious music, but soon turned to a mix of industrial heavymetal, symphonic rock and gothic ambient music on their second album Enter The New World (Cold Meat Industry, 1992). Songs such as To Mega Therion evoke Wagnerian emphasis, opera choirs and symphonic marches.

Sacrosancts Bleed (Cold Meat Industry, 1992) increased the number of samples and of heavy metal riffs (Chaos Breeding).

Sacrosancts Bleed (Cold Meat Industry, 1992) is a feast of excesses. Both the samples of heavy-metal guitar and the stormy beat-boxes are emphasized. The vocals are an agonizing grunt that delivers the blaspheme prayers of Chaos Breeding and Inferno. Havukainen's tour de force runs the gamut from supercharged cerimonies (Fifth Skin) to metallic/industrial concertos (Taste Of Human), from abstract noise pieces (Scum) to sheer horror (Arcanum).
Invocation reprises Laibach's satanic/military sound.
The album peaks with Sacrosancts Bleed, a concentrate of Gregorian litanies, Wagnerian choirs, baroque harpsichord, martial drumming and children's wails.

The fourth album Purgate My Stain (Staalplat, 1995) refined their kind of gothic music for slow tempos, transcendent drones, ghostly choirs, symphonic electronics and visions of satanic monasteries.

Recollection (Cold Meat Industry, 2001) is a career anthology.
