More of that bizarre freaked-out blackness known as "True Sheffield Black Psychedelia"! If you're a junkie for the weirdest, most "out" black metal out there, it's hard not to get pretty obsessed with the Frequency Thirteen catalog and all of the bands on the label that's based in Sheffield, England. All of this stuff is so weird and heavy and blackened and infectious that I've been listening to it constantly over the past few weeks, getting totally immersed in the mutant miasma of krautrock and klosmiche psych and noise-drenched black metal and damaged grindcore that all of these bands spew out, especially the blow-out brainfuck necrokrautrock of Skultroll and the utter mutant mania of Black Vomit. The brand new Black Vomit album Jungle Death was a shoe-in for our featured release this week, but we also have two cd-rs from Frequency Thirteen that pair up Black Vomit with other likeminded bands like the mighty Dukkha and the lysergic buzzblast of Rape Rack!

The Black Vomit / Rape Rack split is a blazing dose of vile whatthefuck heaviness. The disc starts off with Black Vomit, who label their "side" Scumfuck and begin with the eerie windswept ambience of "Dripping Red" that evolves into heavy, fuzzed-out black drone, and then all of a sudden kicks into this bizarre synth/drums metallic hypno-groove, kinda 8-bit and digitized, then goes into trippy, distortion-soaked psychedelic grind with heavily fx-splattered vocals. "Crush Your Day" is a freaked out mess of distorted programmed blastbeats and glitchy, Digital Hardcore like pound, brief stretches of glitchy, angular crawl, and "Witchtrial" moves through weird computerized black ambience, vocoded snarls, spacey drones , and breaks into an awesome, hypnotic krautrock workout surrounded by layers of processed blown-out riffage and trance-inducing robotic blastbeats and fx, the jam sliding back and forth between the motorik robo-pulse and the more ferocious black blast, eventually dropping off into a vast void of meditative blackness punctured by blasts of ultra-distorted low end and murderous screams, finally exploding at the end into brutal metallic blacknoise. Fucking killer!

Going for a more ambient approach, Rape Rack deliver three tracks of their own version of blackened kosmich psych, their music soaring through dense debris-filled realms of drumless drift. Thick swathes of cosmic synth and trippy spaced out electronics, gorgeous murky melodies, caustic corrosive distortion, their nocturnal blastscapes littered with all sorts of decayed and corroded sound, sometimes floating into epic dreamy ambience, sometimes erupting into violent torrents of murky, decomposing black metal that's almost devoid of propulsion. The last Rape Rack track is a sixteen minute epic that drops almost all of the more abrasive sounds from before, a massive shimmering black mass of obsidian blackdrone flecked by digital shards and streaked by swirls of ghostly murmur.

And after all of that, we get a seventh unlisted track that is a collaboration between both Rape Rack and Black Vomit, it's really short, barely three minutes long, but it's a ferocious, super-fucked up blast of overmodulated, mega-processed black metal, the riffs blurred into indistinct shred, bathed in over the top fx, the bestial vocals stretched and blown out into clouds of demonic reverb, a deafening abstract mass of psyched-out heaviness. This rules!
