Your Personal Metal Deep Cuts

Last week we had a great thread about metal without growls. In reading suggestions, and conjuring up some of my own, I re-realized a bunch of stuff.

I wanna see your top 3 metal deep cuts.

What do I mean by deep cut? I mean the formative shit. The stuff you found and loved along the way but lost track of, that when you revisit you go "fuck what happened to these guys?" The ones that helped guide you but fell off the face of the earth (or just your radar).
