Lamb of God is a Grammy-nominated five-piece metal band from Richmond, Virginia, formerly known as Burn the Priest. They have sold over 1 million albums in the U.S. alone.

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. 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.
