These French black metallers deliver a ripping, filthy blast of chaotic, skull scraping black metal with Blasphemy For Satan, one of the more intense black metal offerings we just took in from the Tumult back catalog. Sort of similiar to a rawer, more aggressive old Gorgoroth or a faster Vlad Tepes that's been coated in white noise, Diamatregon keep it in the red, their songs ultra saturated in distortion, generally delivered at 1000 mph blasts but occasionally breaking down into a crushing midtempo part or flatlining into crawling sludge. But Diamatregon are also masters of melody, with awesome hooks behind every song making their satanic noisy BM way catchier than you would expect. There's a killer hyperspeed cover of Misfit's "Death Comes Ripping" towards the end, right before the band sinks into an epic 17-minute jam called "The Beast Is Dead" that takes the band through passages of psychedelic drones and Sabbath riffage, weird samples and harsh noise, stumbling noise-doom and black metal marches. The whole album is 45 minutes long, a highly recommended slab of super-catchy, convoluted black metal weirdness and intensity packaged in a bright black and red case.
