Mutant is/was a side project for two members of the
technical death metal band
Theory In Practice,
here opting to explore black metal.
As one might expect given their pedigree, the musicianship
here is in fine form, almost to the same degree of
complexity as in their other band, yet this is undeniably
black metal and not death metal, with vocalist Henrik
Ohlsson shifting his vocals from a death-ish rasp to a more
standard black metal style here.
The drums are programmed, but they sound more natural than
most other attempts at drum programming, and they certainly
do not detract from the overall sound.
This is probably a one-time affair, though no formal word of
this has been announced.
