These kinds of threads would probably be better in general chat. But anyway... '94 was the peak for black metal, so I'm going with that.
Darkthrone - Transilvanian Hunger
Mayhem - De Mysteriis Dom Sathanas
Gorgoroth - Pentagram
Enslaved - Frost
Satyricon - The Shadowthrone
Rotting Christ - Non Serviam
Impaled Nazarene - Suomi Finland Perkele
Unfortunately by '94 death metal was on a downward trend, but there are still some good (and great) releases from that year.
Incantation - Mortal Throne of Nazarene
Cryptopsy - Blasphemy Made Flesh
Bolt Thrower - ...For Victory
Asphyx - Asphyx
Cannibal Corpse - The Bleeding
Septic Flesh - Mystic Places of Dawn
I'm sure I'm forgetting a lot of stuff.
