The members of Lamb of God originally began collaborating as Burn the Priest in 1990 when Mark Morton, Chris Adler and John Campbell were all living on the same floor of a dorm at Virginia Commonwealth University. Although Morton moved to Chicago after graduation to pursue a master's degree, the band continued on with new guitarist Abe Spear. Randy Blythe was added on vocals when the band decided to expand past its instrumental sound. With the transition from instrumental to vocal music, the previously unnamed band began to operate under the moniker of 'Burn the Priest'. Burn the Priest had been playing around Virginia when Morton moved back from Chicago and re-joined the group.[5] In 1997, Burn the Priest released 2 split seven-inches, one with ZED and another with Agents of Satan. The next year, the band recorded a self-titled full length album with Steve Austin from Today Is The Day fame, it came out on Legion Records on April 13th, 1999. Also, through mp3.com, a compilation CD of singles and other one-off tracks called Sevens and More was released.[6] Abe left the band in 1999 after admitting himself to a rehabilitation center outside of Williamsburg, Virginia.[citation needed] His departure left an opening for a guitarist, which was filled by Chris's brother Willie Adler. After a year of this lineup, the band changed its name to Lamb of God and signed with Prosthetic Records.

After two well received releases and a DVD (Terror and Hubris) on Prosthetic Records, the band signed a new recording contract with Epic Records in late 2003. Their first release for the label, Ashes of the Wake, debuted at #27 on the Billboard Top 200 chart and has sold over 250,500 copies in the U.S. to date [1].

On August 29, 2005, the band announced that their DVD Killadelphia, which chronicles the band on tour supporting Ashes of the Wake, had received Gold certification from the RIAA. The DVD features a complete live performance at the Trocadero in October 2004 in Philadelphia, and also contains three of their music videos, commentary by the band, outtakes, soundchecks, and plenty of backstage shenanigans.

On January 25, 2006, a press release announced the re-release of Lamb of God's debut album, New American Gospel. The original, along with the self-titled debut Burn the Priest, were both produced by Steve Austin, known for his work with Today Is the Day, Converge, and Unsane. The re-release was remastered and repackaged with four new tracks, exclusive liner notes from the band and a re-imaging of the album art by longtime band collaborator Ken Adams. The album was re-released on April 4, 2006.

Their newest album, Sacrament, was met with immediate success, debuting at #8 on the U.S. Billboard charts. The same day Sacrament was released, the band's fan club The Congregation was launched. Before the release of Sacrament, the band took part in the 2006 The Unholy Alliance tour in North America with Slayer, Mastodon, Children of Bodom, and Thine Eyes Bleed, and in Europe with In Flames instead of Mastodon. After Sacrament was released, they joined onto the North American portion of Gigantour, headlined by Megadeth and including Arch Enemy, Opeth, and Overkill. They were touring Europe.

They have also toured with Trivium, Machine Head, and Gojira. They have also been long time friends with the band GWAR, having come from the same city and most members from the same college.

Lamb of God has been nominated for a Grammy Award for "Best Metal Performance" for the song "Redneck" from Sacrament in 2006 for the 49th annual Grammy Awards.

On February 9, 2007 Lamb of God made their national television debut on Late Night with Conan O'Brien. They played "Pathetic" from Sacrament. On February 29th, the band was confirmed to play the UK's Download Festival 2007. The band is also confirmed as one of the headlining acts in this year's Ozzfest tour alongside Ozzy Osbourne, Static-X, and Lordi.
