Warm Springs - They Lose Their Common Sense
Cover
Definitely the side project of a member of a death metal band, most likely the drummer or bassist. The album consists of two long-form (untitled) ambient pieces, in stark contrast to the material the artist is more generally known for and associated with.
Anyone buying the record would get a shock if they decided to check out the material of the original group (probably called 'deathmetalhammerslayerfistwarrior' or something) whereas the mere existence of this record is deeply divisive to the band's 'original' fans.
(this has actually happened - Mick Harris of Napalm Death is now doing dark-ambient/DJ stuff)
