The original CD release contained 16 bonus tracks taken from the Reek of Putrefaction album. Some editions also contain "Genital Grinder II" and "Hepatic Tissue Fermentation" from the Pathological compilation. The album was reissued in 1996 with a censored outer cover proclaiming "Original artwork contained inside". It was later reissued in 2008, as part of reissuing of all of Carcass's albums to tie in with their reunion. This version included the Symphonies of Sickness demo as bonus tracks on one side of a dualdisc, while the DVD side featured the second part of an extended documentary titled The Pathologist's Report Part II: Propagation. Later editions of this reissue contain the songs on a CD and the documentary on a separate DVD. This reissue was presented in a 12-panel digipak with full lyrics and artwork.

Carcass' debut album Reek of Putrefaction is said to have spurred the British Grindcore with its precise riffs and outrageous guitar solos. [...] Carcass' following album, Symphonies of Sickness, featured slower and catchier songs, and showed the band's movement into the Death Metal genre.
