Thy Art is Murder started in 2006 in Blacktown by vocalist vocalist Brendan van Ryn, guitarists Gary Markowski and Sean Delander, bassist Josh King and drummer Lee Stanton. They released their demo entitled “This Hole Isn’t Deep Enough for the Twelve of You” and released an EP in 2008 called “Infinite Death.” The band set out on extensive touring and after two years van Ryn departed the band; unfortunately it took a year for the band to find another lead singer, Chris “CJ” McMahon. Also, bassist Mick Lowe replaced King early in 2010.
On 16 July 2010 Thy Art is Murder released their first full-length album entitled “The Adversary.” In 2011 founding member and lead guitarist Gary Markowski departed from the band and Delander decided to switch from guitar to bass, making way for Andy Marsh and Tom Brown on guitar. After touring in Europe, the band went back into the studio to record “Hate” which they released on 18 October 2012. “Hate” debuted at number 35 on the Aria Charts and reached number 1 on AIR. After the release of the album, the band set out on tour and made a number of appearances at music festivals. In early 2014 the band made headlines when McMahon encouraged fans to get onstage during their set on Brisbane leg of theSoundwave Festival tour resulting in the band getting dropped from the tour. This however, did not stop their forward movement and they continued to travel and play their live gigs.
