Considered to be one of the leading death metal bands to emerge from Poland in the 1990s, Behemoth has endured quite a few lineup shifts during their career (especially in the bass department), with founding singer/guitarist Nergal being the only constant member. Behemoth was formed during 1991 (originally as a trio), and began issuing several demos shortly thereafter, the most circulated one being 1993's From the Pagan Vastlands. The same year, Behemoth issued their debut release (via the Italian independent record label, Entropy), And the Forests Dream Eternally. Two years later, the group released their first full-length recording, Sventevith, which received favorable reviews by the metal underground press. For 1996's Grom, Behemoth widened their musical vision by experimenting with acoustic guitars, synthesizers, and female vocalists, but all the while retained their brutal, extreme metal sound; leading to the group's inaugural full-on tour of Europe. 1997's three-track stopgap EP, Bewitching the Pomerania, proved to be the first recording to feature drummer Inferno, who would soon become a driving force (and permanent fixture) in Behemoth.

Their fifth release overall, Pandemonic Incantations, was issued a year later in 1998, as Behemoth continued to average at least one lineup change per release. Behemoth's last release as a trio (and first for new label Avantgarde), 1999's Satanica, continued to expand the group's following among the black metal masses, as they secured supporting slots on two separate tours with leading bands of the genre: Deicide and Satyricon. Behemoth's first release of the 21st century, 2000's Thelema.6, saw the group's lineup expand to four members for the first time, as newcomers Novy (bass) and Havoc (guitar) signed on with stalwarts Nergal and Inferno. The album proved to be the first of the group's career to receive worldwide distribution (issued in the U.S. a year after its initial release), and also featured Nergal collaborating lyrically with outsider Krzysztof Azarewicz. Behemoth embarked on their most substantial tour yet, playing shows alongside the likes of Morbid Angel and Nile, and even launched a few headlining tours on their own. In 2002, a home video/DVD was issued (recorded in their homeland of Poland), The Art of Rebellion: Live. ~ Greg Prato, All Music Guide
