Gruntsplatter I have known for a couple of decades. Underneath The Deadlight is a new project to me, and (I think) a new project in general. Discogs has only one release listed which is also from 2022 (and released on Gruntsplatter’s label Crionic Mind!). The project’s Bandcamp has six. Discogs has them listed as “dark ambient, industrial”.
A quick scan shows that UTD makes guitar based drone noise, so I guess that explains the amount of guitar on “Predation Monoliths”. The guitar wall of noise with stretched sounds and highly distorted vocals is actually pretty damn good. Perhaps this release is should be more lined with bands such as Khost, Sutekh Hexen or Gnaw Their Tongues than with the ambient death industrial of (early) Gruntsplatter.
There are several platforms where you can listen to the album before deciding whether or not to buy it. I may need to listen to the other releases of UTD as well.
