Pestilence began in the Netherlands in the mid 1986 as a thrash metal band. The lineup, consisting of Patrick Mameli (guitar, vocals), Randy Meinhard (guitar), and Marco Foddis (drums), recorded two demos before gaining the attention of Roadrunner Records. After the first demo, Martin van Drunen (bass/vocals) joined them. These two demos - Dysentery (1986) and The Penance (1987) - are raw, sounding mostly like a cross between Possessed and Schizophrenia-era Sepultura. After signing to Roadrunner Records, Pestilence released their debut album titled Malleus Malficarum in 1988, further refining their approach to thrash metal. The new material was tighter and more focused than the demos. Shortly thereafter, guitarist Randy Meinhard left the band to pursue other musical goals in a new band named Sacrosanct.

Meanwhile, Pestilence recruited a new guitar player by the name of Patrick Uterwijk. In 1989, the band released their second album Consuming Impulse, which was a turn toward to death metal. From a musical standpoint, things became heavier and more haunting. Vocally, Martin van Drunen moved away from cleaner vocals in favour of a more acidic growl. With its release, Pestilence gained international attention, highly regarded worldwide by death metal fans community. But before a follow-up album was released, the lineup changed once again vocalist and bassist Martin van Drunen departed to front Asphyx.

Pestilence were faced again with the challenge of replacing a member, being without a vocalist and bassist. So while recording their third album Testimony Of The Ancients (1991), they enlisted bassist Tony Choy, who at the time was playing with the technical death metal band Cynic and Patrick Mameli took over the vocal duties. With this lineup, they released the album Testimony Of The Ancients. The new material was not as abrasive as the previous albums, but the band's musicianship has obviously grown and the album had the best production job of the band's catalogue.

However, Tony Choy was never a permanent member, and ended up going back to Florida to eventually play with Atheist. In the meantime, Pestilence enlisted the talents of Jeroen Paul Thesseling.

Over the years, the Pestilence members were getting into other forms of music, primarily jazz-fusion which, the band wanted to pair with metal. The band's fourth and final album, Spheres was released in 1993. With every album, Pestilence went through some kind of a change and Spheres was no exception. Pestilence mixed jazz-fusion elements into their death metal style, and used guitar synths throughout the album.

Pestilence's popularity had risen with the release of each album, but unfortunately, so did tensions between the members. So after a short period of time, the band unanimously decided to split up, feeling they had reached their creative climax.

In 1994, Roadrunner released one last CD from Pestilence: a best-of titled Mind Reflections, containing tracks from all four albums, plus the extremely rare song "Hatred Within" (originally released on the Teutonic Invasion Part II compilation) and six unreleased live tracks recorded in at the Dynamo Open Air Festival in 1992.
