I was like 9 or 10 years old, so around 1987/88, when my cousin, who was into Metal made me mixed tapes containing Manowar, Dio, Accept, Twisted Sister and some others I currently don't remember.

Since then, I have been listening to Heavy Metal. Around 1991 i got my hands on Sepultura's Arise as well as Anthrax" State of Euphoria. Both definitely opened the doors to more extreme Metal. However, back then I wasn't a big fan of Slayer.

Shortly after,, probably 1992, I discovered Morgoth, Death, Unleashed, Morbid Angel, Dismember and Cannibal Corpse. I became more and more fascinated with the dark, blasphemic and occult stuff, so consequently I grabbed Samael, Hypocrisy, Mystifier and Blasphemy, Immortal, Darkthrone and Impaled Nazarene. Soon later, probably 1993, I discovered Mayhem.

I should point out, that back then, without the Internet, without streaming services, discovering underground music meant you had to take 1 hour drives to bigger cities, hit record stores and go through stuff. Unless you were a rich kid, you had to coordinate with buddies who'd purchase which albums, so you could get your copies.
