I can definitely see, though, how his style could be a bit of an acquired taste. He makes some very unusual melodic choices often choosing a very minor-key, almost in straight up Locrian mode in some places, and when it happens over a more Dorian-oriented riff it's a little bit angular sounding, almost "flat" sounding sometimes. I don't know if it's intentional or not.
Also, I love, love, love how the vocals are mixed here. It's only a single voice but he sounds fucking massive and insanely powerful
