most of the /mu/core metal stuff is a pretty good place to start, there are definitely some records that /metal/ jerks off that i absolutely do not give a fuck about. What are you trying to get out of metal? What kind of music do you primarily listen to? Metal is very very very vast, and subgenres of metal can differ very very greatly.
Try some of these friend (not going into death metal here, as thats kinda an acquired taste imo).
Just some basic examples which I find pretty good to start w/
Cryptopsy - None So Vile (1996)
Electric Wizard - Dopethrone (2000)
Leviathan - Scar Sighted (2015)
Opeth - Morningrise (1996)
Blind Guardian - Nightfall in Middle-Earth (1998)
Burzum - Filosofem (1996)
I think all these albums are fantastic, especially for people new to the genre
