Necroticism – Descanting the Insalubrious is the third album by Britishextreme metal band Carcass. It was released on 21 October 1991 through Earache Records. This album is the first to feature guitarist Michael Amott. Many of the tracks describe economical ways to dispose of dead bodies.
Ken Owen and Jeff Walker said during The Pathologist's Report Part III: Mass Infection that they rejected the descriptions of Carcass's music on this album being grindcore. While Owen acknowledges its death metal characteristics, both he and Walker expressed that they are more inclined towards calling their music on this album "progressive".
Necroticism was originally released on 21 October 1991 through Earache Records. The album was re-released in 2008 as part of an ongoing series of Carcass reissues, to tie in with their reunion. The main album is presented as one side of a dualdisc, while the DVD side features the third part of an extended documentary titled The Pathologist's Report Part III: Mass Infection, and a 23-minute interview with Walker and Amott from 1993, recorded on the Gods of Grind tour. Later editions of the reissue contain the album on a CD and the documentary on a separate DVD. Also included in the reissue is a set of four art cards. The reissue is presented in a 12-panel digipak with full lyrics and artwork.
