I’m keen to see the answers to exodus’ questions above - similarly I’ve helped others navigate these waters in the past. I have a few first thoughts that may be well off-base, but:
Maybe some Sodom for similar thrash/grind vibes:
Or for one maybe out of the proverbial left-field, not even really “metal” but perhaps Acumen Nation:
Other bands I’m thinking about include: Kreator, Testament, maybe Arch Enemy, maybe early Anthrax.
Stuff that I think is just rad and reckon is worth a listen anyway, and might get there depending on how you feel and some of those questions pan out: Swallow the Sun, Ghost Brigade, Insomnium.
I could recommend everyone maintains a healthy dose of Judas Priest, also.
