Exhumed was formed in the US in 1991 by Matt Harvey (guitar, vocals), Col Jones (drums), Derrel Houdashelt (guitar), Jake Giardina (vocals) and Ben Marrs (bass). They soon entered a studio and recorded their first demo, "Excreting Innards", which consisted of six tracks. It was released in the start of 1992 along with two other demos, "Dissecting the Caseated Omentum" and "Goregasm". In 1993 the 7" EP "Excreting Innards" was released and shortly after the band began playing live. Ben was eventually forced to leave the band, but Jake took over bass duties along with vocals. The demo "Cadaveric Splatter Platter" also followed in 1993 along with "Grotesque Putrefied Brains" which was the last release to feature Jake since he left the band. He was replaced by Mark Smith (vocals) and Matt Widener (bass). Marks stay was short and he was replaced by Ross Sewage.
