I'm surprised you didn't list Possessed, the band that invented Death metal (named it with the demo Death Metal earlier the same year Death changed their name from Mantas to Death), and the death growl, the deep style of Death Metal vocals.

Also, Mayhem/Burzum, for even making Black Metal a thing, past a few first-wave bands.
