In my opinion, of course, but I'm interested in your views of the most significant, influential and important metal releases...not a favorites list!
Black Sabbath-Black Sabbath...of course
Stained Class-Judas Priest...I think this album separated and defined the genre
Melissa-Mercyful Fate...first real in your face evil
Kill 'em All-Metallica...most important moment in thrash
2112-Rush...early epic concept album
Images and Words-Dream Theater...an original with many imitators to follow
Speak English or Die-SOD...hardcore+metal+humor...an original concept
For guitarists
Van Halen-Van Halen...Eruption, nuff said...changed the approach to the instrument forever
Bizzard of Ozz-Ozzy...introduction of Randy Rhoads
Rising Force-Yngwie Malmsteen...first full neo classical shred release
I'm sure there's lot's more.
