Damn this is my whole thing!!
Early Venom, Bulldozer, Bathory's self-titled, Sodom's In The Sign Of Evil EP, Celtic Frost, Schizophrenia (Colombia), Witchtrap - if you are after something with a blackened twist.
Znowhite, Exciter - for more of a speed metal vibe.
Cryptic Slaughter, Excel, D.R.I., Carnivore's Retaliation - for some crossover (thrash/hardcore punk fusion).
Whiplash, Hallows Eve, Sepultura's Morbid Visions, Onslaught, Razor, Sodom's Masquerade in Blood, Tankard's Zombie Attack, Voivod's War and Pain - if you are after some old-school goodness.
Violator, Lich King - newer, but stiff raw af and will kick your ass back to the 80s.
There's tons upon tons of shit I've uploaded to !thrashmetal@lemmy.world over the years. Let me know if you ever need any more recs, I'm a total fucking nerd when it comes to thrash 🤣! 🤘🤘
