[1] Broadrick's usage of the title spans back to his work in the 1990s with Kevin Martin in Techno Animal, but he first released a solo studio album as JK Flesh in 2012.

[5] While this influence is felt in some of his more prominent releases, like in Godflesh's 1991 EP Slavestate and 1992 album Pure,[6] Broadrick fully explored these genres privately in a solo capacity or incorporated the work into his collaborative projects such as Techno Animal with Kevin Martin.

[7][8] In 2009 Broadrick compiled some of the JK Flesh tracks he created from 1997 to 1999 in an album named From Hell released under the title Krackhead, but it wasn't until 2012 that he fully embarked on the project.

The project's debut album, Posthuman (2012), still features heavily downtuned guitars, thick distortion, and a bleak mood–aspects all common in Broadrick's other music–but the beats are less industrial and more dance- and techno-oriented.

[17] Broadrick has also credited Moritz von Oswald's dub techno projects Basic Channel and Maurizio as well as his record label Chain Reaction as a main influence on JK Flesh.
