2006–2008: Formation, demo and Infinite Death EP Formed in 2006, in the Western Sydney locality of
Blacktown, the group originally consisted of vocalist Brendan van Ryn, guitarists Gary Markowski and Sean Delander, bassist Josh King, and drummer Lee Stanton. Most members were around 15 years old at the time. and began playing local shows. They quickly gained a loyal fanbase among local deathcore fans in Western Sydney due to their highly energetic performances, and went on to independently tour the east coast of Australia. After touring they returned to the studio to record their first EP
Infinite Death, of which all lyrics were written by Brendan van Ryn after the instrumentals were recorded.
Infinite Death was released in 2008 via Shock and subsequently Skull And Bones Records. The
Infinite Death EP was also published on the band's official
Myspace page, leading an explosion of popularity around the world. The album gained notoriety due to the technical nature of their deathcore sound, and also their
sacrilegious and
misogynistic lyrics. The EP reached number 10 on the
AIR Charts. However, McMahon, the group's now former vocalist, explained in 2013 that van Ryn was removed because "he couldn't sing [anymore] and he had a massive attitude problem." Thy Art Is Murder searched for a year for a new vocalist, until finding Chris "CJ" McMahon from Sydney
metalcore band Vegas in Ruins. The band were so impressed with his
death growl vocals that he was incepted into the band during 2009. Bassist Mick Lowe replaced King shortly before the band began tracking demos for their first full-length album
The Adversary. The demos recorded in 2009 included early versions of the songs "Engineering the Antichrist" and "Cowards Throne". In 2010, the group began recording the album's final recording sessions and released the album on 16 July 2010. Thy Art Is Murder supported the release of
The Adversary with Canadian deathcore band
Despised Icon's Australian leg of their Farewell Tour, which also included
The Red Shore.
2010–2014: Hate Late 2010 saw further line-up changes, notably the dismissal of founding member and lead guitarist Gary Markowski due to allegedly stealing from the rest of the band members.

Rings of Saturn had in fact won the vote by 1%. Eventually, promoters chose to include both bands. On 17 June 2013 the band revealed they would be touring across Australia with

Download Festival 2014. The band made Australian news headlines in late February 2014, when McMahon encouraged fans to get onstage during their set on Brisbane leg of the
Soundwave Festival tour. Promoter AJ Maddah later tweeted his decision to take the band off the rest of the tour calling them "disrespectful arseholes" and claiming that McMahon had told the crowd that "there are thousand of you and dozens of security. Smash them. All of you get on the stage". Fan footage uploaded on
YouTube revealed that Maddah's version of McMahon's pre-song speech were embellished. The following day both the promoter and the band tweeted that Thy Art Is Murder would be allowed to play the remainder of the tour. McMahon later commented on the incident, saying "it's just all bullshit... I just wanted the crowd participation, wanted people to try and make their way up on-stage and have a crazy show"; however, he also expressed positive feelings to the aftermath as he felt the coverage of the incident gave the band free publicity. The band announced their participation in the Mosh Lives tour, headlined by
Emmure, travelling the US in March and April 2014. The band headlined a short Canadian tour with Sworn In in April 2014. The band played New England Metal And Hardcore Festival in April 2014. The band also took part at the Summer Slaughter the same year.

Slayer on 2015's
Mayhem Festival, which toured the U.S. from June to August.

On 14 January 2017, former vocalist McMahon rejoined the band onstage at Unify Festival in Tarwin Meadows, Victoria, where he confirmed his return to the group, and that the show was for the fans a "celebration that is me coming back to join my brothers in world domination." The band released their fourth studio album, titled
Dear Desolation, on 18 August 2017. In an interview in October 2017, guitarist Andy Marsh confirmed that if McMahon had not returned, they would've recorded

Nuclear Blast Records. On 30 October 2020, the band released a single titled "Killing Season" which guitarist Andy Marsh explained was about

On 9 May 2023, the band published the lead single "Join Me in Armageddon" and an accompanying music video. At the same time, they officially announced that their sixth studio album,
Godlike, was set for release on 15 September 2023, whilst also revealing the album cover and the track list. On 11 July, the band unveiled the second single "Keres" and its corresponding music video.

Godlike, Thy Art Is Murder revealed on social media that they fired vocalist CJ McMahon without his knowledge. The album features re-recorded vocals from a then-unknown vocalist with McMahon being removed from the album. McMahon was only aware of his removal after the band released a statement, indicating that the band had made the decision to replace McMahon's vocals while he was still in the band. According to a statement from the band, the split is partially due to McMahon's "recent
anti-trans comments", which they note were only a symptom of a larger problem. On 27 September, the band announced that they had recruited Tyler Miller of
Aversions Crown as their new full-time vocalist. On November 5, 2024, the band released the single "Through Blood I Purify”. ==Musical style and influences==
