Very Intrigued by Heavy Metal lately

I'm thinking of getting into metal/hard rock. Could someone direct me to some titles or albums to try?

Morbid Angel - Blessed Are The Sick (original version only, NOT the remaster) is my favorite metal album, as it's the only one I've heard with such awesome high dynamic range mastering.  I'd love to hear more metal mastered in this style. LOUDER DOES NOT MEAN HEAVIER.
