Hi, Mike.
Dunno about 45 rpm but if that isn't essential and you are talking about early "proto" rather than more modern shredding, I can offer the following:
the old Dutch pressing of Sabbath's Heaven and Hell (Vertigo);
the first four Sabbath albums on UK Vertigo Swirl;
Iron Maiden Number of the Beast mastered by Wally T;
First Lucifer's Friend album on German Philips;
Scorpions Lonesome Crow- if you don't want to spring for the original Brain pressing, the slightly later Metronome/Brain sounds good, just doesn't have the cool label;
Opeth- Damnation from the twofer- Deliverance and Damnation (S.Wilson remaster);
Josefus- Dead Man- just buy the current reissue, original pressings are collectible and expensive;
Randy Holden Pop II-- they will almost all be reissues or boots-- one of the loudest acts in the business, monster guitarist; just reissued again;
Atomic Rooster-Death Walks Behind You- (not really metal but heavy, rich organ and dark, gothic sound); original UK pressing with Wm. Blake painting sounds dramatically better than the much cheaper US pressing with a different cover.
