Grey Matter Productions says:
Corona Barathri is a group of devout Luciferians from Russia and Ukraine who perform and record ritual invocations dedicated to the Diabolus. The group has collaborated with ritualistic musicians such as the infamous Michael W. Ford and under the banner of great ritual ambient labels like Black Mara Records. Nox Mali was recorded on the eve of the Great Sabbath and contains a collaborative track with fellow Luciferian ritual ambient group Antelogos, out of France. The track is 21 minutes of dread-induced hypnosis. The swirling and startling strings that sit atop a layer of thick and foggy drone set the mood. Ritual ting-shas, Tibetan singing bowls and a steady flow of light and airy chimes complement the atmosphere by inducing a sense of something greater being called to the forefront, as Latin invocations are both spoken and sung. Suddenly the mood shifts, massive pounding drums are introduced, terrifying the soul. Waves of thunderous distorted noise move in and out of audible range, as if the devil himself were breathing down your neck. All this, only 6 minutes into the ritual invocation.

A few words from Corona Barathri:

Flame borned by Darkness reflects in black hearts,
Spirit filled with Evil is embodied in black souls.
Devil’s tribe, Sons of Nahema,
Cursed by light, marked with the seal of Hell,
Heirs of the Great Abyss.

Night of Evil, Night of the Nights, Night of the Triumph of Evil Force, Feeding the Fire with our blood.
Samael is the Father of Sins, the Source of Death.
Childs Of Nahema – Sons of Perdition, Dark Warriors, curse to god, curse to the world, curse to mankind.

Keep Black Fire Burning!
Honor Satan with your shed blood, evil word and evil deeds!
One Heart – One Essence.
