Black Vomit for Experimental/Post-Metal

Black Vomit is the British experimental black metal project of Dave OBM, co-founder of the Frequency Thirteen (Freq13) record label and based in Sheffield. Dubbed "True Sheffield Black Psychedelia," Black Vomit plays a unique blend of noisy, grinding black metal mixed with IDM, krautrock and dub influences, with songs often lapsing into dark and hypnotic kosmische drift, with slowed down and distorted voice samples enhancing the hallucinatory atmosphere. Black Vomit released two splits before issuing their debut and most well-known album Jungle Death on Rusty Axe Records in 2009. Dave OBM, presumably using the moniker Mndeathfreq, was accompanied on this release by two mysterious fellow Freq13 musicians: Ghettodweller on bass with guitar and vocals handled by C12H16N2 (named after the molecular formula for DMT, highly-magnified crystals of which adorn Jungle Death's cover art). As with their first two CD-Rs, Black Vomit's sophomore LP, Let it Come Down, was released on Frequency Thirteen in 2011, where the project began subtly incorporating dub and dubstep elements.

Comparisons prove difficult, as Black Vomit sounds like some impossible mix of Igorrr, Aluk Todolo, Tim Hecker, Pharaoh Overlord, Oranssi Pazuzu, Lightning Bolt, Yoga and Goblin.

I haven't been able to verify if this is actually them though.
