there's not much talk that i see of genres like noisegrind or gorenoise, so hopefully there's others who know about it.
main ones that i know about are Last Days of Humanity and Encenathrakh.
LDOH is moreso goregrind with an extremely noisy production, while Encenathrakh is brutal death metal taken to the extreme. comes out as some hybrid of noisegrind and deathgrind with BDM vocals.
i know the people here are mainly about harsh noise and power electronics but i dunno.
