Anaal Nathrakh are a British black metal band, formed in 1999. They are signed to Season of Mist Records.
The name comes from Merlin's Charm of Making in John Boorman's Excalibur (1981). Given Michael Everson's transcription, Anaal Nathrakh means "serpent's breath".
Anaal Nathrakh are typically described as either black metal or post-black metal; they ascribe to the latter, mainly in their aesthetics: dressing in a casual manner, as opposed to the theatrical corpsepaint and spiked leather clothing traditionally favoured by the black metal subculture.
The band originally started as a raw black metal band, and with the release of Domine Non Es Dignus, they have shifted more towards a blackened death metal fusion sound. Through the use of distorted samples, sound effects and programmed drums, much of their work also falls into the industrial metal category, though they use no keyboards in their work. Some Anaal Nathrakh fans, and at times, Anaal Nathrakh, refer to the group's music as "necro metal."
