'91 Death Metal.
I'm not prepared to provide a list right now, but it was damn good.
Off the top of my head I know Blessed Are The Sick, Effigy Of the Forgotten, and Necroticism - Descanting The Insalubrious came out that year, which are all in my Top 5. Plus Death's Human which is in my Top 10. And many more great albums.
