Australians Siberian Hell Sounds and Convulsing are perhaps two of the most punishing, dissonant, and avant-garde black metal entities out there, and they’ve joined forces on this split release, each providing a song over twenty minutes long to feed this beastly behemoth of a record. What results is not so much a split as it is a collaborative effort to bring forth to the altar a worthy sacrifice. And worthy it is, as it pleases us with its long, winding and unconventional song structures, its sickening harmony, its thick and heavy atmosphere put on our shoulders to burden, and its incantations spewed from the mouths of madness. Truly, I need not say more, as the music should speak for itself from that point on. Siberian Hell Sounds have returned from Svengali with a bang, and Convulsing establish themselves as a force to be reckoned with, after their impressive debut Errata.
