Slayer - Show No Mercy
My pick for best debut album by The Big Four and one of the most important records for extreme metal everywhere. I'd say this release had just as much of an impact on the formation of black metal that Venom's first couple of albums did. Not to mention that the album is chock full of kickass heavy fucking metal. You have to wear leather and spikes when you listen to this album.
