So what sorts of classical music do people who like any sort of death metal enjoy? Is there any correlation?
Me - post war Avant Garde.
Yeah, me, too. The gloom and doom, complexity, and the dissonant aspects seem to overlap. I was listening to a lot of Penderecki and Xenakis, Second Viennese School stuff before getting into death metal. I just had the craving for more and more dissonant music.
(a fun little bit to check out- one of the most respected death metal bands of all-time, Necrophagist, doing an homage to Prokofiev's Romeo and Juliet at the end of this song:

I also think prog metal and late Romanticism is highly linked. Both have some of the most intensely soulful passages of music, while also being extremely variety-oriented (Haken, BTBAM, Leprous, for example)... they remind me what would a modern incarnation of Mahler would be like...
And of course, the countless neoclassical stuff in metal (Fleshgod Apocalpyse, etc.)
I really want to go to a metal show again, it's been one year since last time when I saw Nile live. I really want to see Cannibal Corpse next. The vibe that you get from the music being played is just unrelenting evil, and I love it lol, it's so much fun.
