[7][8][9][10] Patrick Kennedy of Allmusic compared the band to Pantera stating, "The essential signatures of post-Pantera metal are in abundance on Lamb of God's inaugural album.

[12][13][14] Kirk Miller of Rolling Stone gave the album three out of five stars, writing that "unlike many of their overreaching, Slipknot-influenced contemporaries, Lamb of God deliver a meticulously crafted metal assault.

[15] The band was part of the first Headbangers Ball tour, where they recorded a DVD including live performances and a documentary, titled Terror and Hubris.

[21] Johnny Loftus of Allmusic praised the album, saying "With the genre getting clogged by PVC goofs and Alice in Chains impersonators, Lamb of God balances the equation of power, rage, tradition, and craft.

[22] Ashes of the Wake eventually became their first Recording Industry Association of America certified studio album, being awarded gold status in February 2016.

[19] The album received generally positive reviews, with Cosmo Lee of Stylus Magazine stating, "Sacrament has the band's most memorable songs to date.

"[36] Ed Thompson of IGN referred to Sacrament "one of the best metal albums of 2006",[37] and Jon Pareles of Blender called it a "speed rush all the way through".

[39] The band appeared on major tours to support the album, including The Unholy Alliance with Slayer, Mastodon, Children of Bodom, and Thine Eyes Bleed,[40] Gigantour, supporting Megadeth;[41] main stage at Ozzfest;[24] an appearance at the Download Festival, and an exclusive co-headlining tour with Killswitch Engage, Soilwork, and DevilDriver, where Killswitch Engage and Lamb of God shared headlining spots alternately each show.

[49][50][51] The DVD is a double-disc and has nearly five hours of footage, containing the feature documentary Walk with Me in Hell and multiple live performance extras from the Sacrament World Tour.

[80] Blythe was charged, in the Prague 8 district court, with committing intentional bodily harm after an incident in which 19-year-old fan Daniel Nosek climbed up onto the stage with him.

[83] According to a verdict delivered by the Municipal Court in Prague on March 5, 2013, Blythe had thrown Nosek off the stage and had moral responsibility for the fan's death but he was not criminally liable.

[89] By September, however, Blythe revealed that he was planning to release a new Lamb of God record, which uses lyrics he had written while he was incarcerated along with his book, Dark Days: A Memoir in early 2015.

[93] On November 14, 2016, Lamb of God released a new EP titled "The Duke", which featured two new songs from the VII: Sturm und Drang recordings and three live tracks.

The title track is dedicated to a fan and friend of vocalist Randy Blythe, Wayne Ford, who died after a five-year battle with leukaemia.

While Adler had largely recovered to rejoin Lamb of God in time for its summer 2018 tour with Slayer, further complications from the injuries forced him to take a leave of absence from the band in July.

[103][104] On October 23, 2019, Adler released his own statement about his departure from Lamb of God revealing that he "did not make the decision to leave my life’s work" and he "is unwilling to paint by numbers".

[105] On February 5, 2020, the band released "Checkmate" as the debut single from their self-titled album, Lamb of God, which marks the first song to feature Cruz.

[109] In a September 2020 interview with Australia's Subculture Entertainment, Lamb of God guitarist Mark Morton was asked how he was spending his coronavirus downtime.
