Warthur Inquisition by this point had more or less settled on a style - take croaky vocals, Satyricon-styled classic second wave black metal, and outrageously psychedelic occult and mystical themes, and blend them all together and what do you get? Apparently, the answer is "Ominous Doctrines of the Perpetual Mystical Macrocosm", and whilst it's not too different from Inquisition's preceding albums it's a fun enough listen. Dagon's vocal style takes some getting used to, sure, but the same is true both of "standard" black metal vocal styles (remember when you first listened to this stuff and it sounded super weird?) and all the truly unique and special vocalists in the subgenre like Atila or Dead, and when you combine a vocal style crammed with that much personality with competently executed black metal you are usually in for a treat.

Those who prefer to avoid NSBM releases if possible should note that the album bears the artwork of "Antichrist" Kramer, a big supporter of the NSBM scene, and came out on No Colours (who aren't an official NSBM label but equally aren't very picky about who they sign); since its release Dagon's convictions over child sex abuse images have also come to light. Star rating is based on music only, I leave it to you to decide whether or not you want to pay money for this. Personally, I think there's plenty of black metal out there in this general style which doesn't involve such baggage.
