England's Carcass are an extreme metal band credited as pioneers of grindcore and melodic death metal. With their 1987 demo Flesh Ripping Sonic Torment and their 22-song debut full-length Reek of Putrefaction a year later, they showcased a brutal, physically punishing, technically demanding playing style with gory, violent, and, more often than not, repulsive lyrics drawn from industrial manuals, medical textbooks, societal aberrations, and politics.
