If this makes you feel like lighting a couple of candles, and preparing for an unholy ritual, I would suggest using "Kadosh", Spectrum Mortis' latest EP, as a soundtrack.
From the first notes, it's clear that this is a very honest record; these Spanish doomers are true believers of the art of darkness, their mission to facilitate satanic rituals.
Stylistically, the music is blackened death/doom metal, at times reminding me of Gothic-era Paradise Lost - which is a very good thing. Each song has its own central doomy riff (played in unison, often drenched in reverb) which is then elaborated on. About halfway, however, the songs kick into high gear, with blastbeats and tremolo riffing. Singer Sheram, who also plays bass, has an agressive growl, and sings (or sometimes declamates) most of his texts in Latin.
Highlights of this EP are the second song, Fiat Lux, and the third one, Et Filius Aurorae. This record has a high replay value, and will be present in my playlist for a couple more months. Recommended.
