No Satan, no go for me either Hungdog. And General, I am a classically trained musician (trombone, tuba, electric bass, and upright bass) with extensive music theory education, but I'm not down with most atonal music. I haven't checked out Ad Nauseum, not going to either. I can tell from the description that I won't enjoy it. Don't care much for Portal or their Ilk (looking at you Altarage) either. Imperial Triumphant and Pyrrhon can fuck right off too. About the only thing along those lines I do like is Teitanblood. I equate most of that stuff with free jazz, which I admire but can't listen to and enjoy save for a few exceptions.
Stuff like Immolation and Gorguts are completely different to me. Those guys bring atonality and discordance into somewhat recognizable song structures that you can remember. Bop your head to even. It's still musical to my ears whereas the other stuff is not. And total transparency for our new brethren, the MFi gang know I'm a huge Immolation fanboy. Favorite death metal band of all time for Navy here. The only starstruck moments I've ever had were meeting Rob Vigna, Ihsahn, and Samoth (Emperor is another huge favorite).
BTW - glad you liked that Pale Swordsman. It's definitely influenced 2nd wave stuff without being derivative. I'll take that crust dump as my reward for helping turn you on to it 😉.
And I had also named JohanV "Johnny 5" in my head. Even picture the little robot when I'm reading his posts.
