Necroticism – Descanting the Insalubrious is the third studio album by English extreme metal band Carcass. It was released in Europe by Earache Records on 30 October 1991 and in North America by Relativity Records on 11 February 1992. This album is the first to feature guitarist Michael Amott and marked the first time Carcass had recorded as a four-piece. Many of the tracks describe economical ways to dispose of dead bodies. Necroticism continues the move towards a predominant death metal sound which was started in Symphonies of Sickness, featuring songs with longer sections and complex structures, more akin to the then-burgeoning technical death metal subgenre.
