In the summer of the same year, Julien-K toured as direct support for the band PIG, which consists of former members of the pioneering industrial rock outfit KMFDM. They were also joined by electro-rock band Ghostfeeder. On July 18, 2018, they announced their fifth album, Harmonic Disruptor via another Indiegogo campaign. The album's concept is a homage to the style that Julien-K were known for when they first started out as a group, during the Death to Analog era, with a much darker and heavier industrial metal sound. It was eventually released on 17 April 2020. Collaborations Julien-K teamed up with the late Chester Bennington, former Linkin Park lead vocalist, to perform the song "Let Down" for the ReAct Now: Music & Relief televised concert. The Julien-K production team of Derakh, Shuck and Valcic also worked with Chester Bennington to perform an exclusive version of the song "Morning After" for the Underworld: Evolution soundtrack and for the remix album of the band Mindless Self Indulgence's "What Do They Know?". The track was released as a bonus remix on Another Mindless Rip Off, with a completely "Instrumental DJ Dub" version being released for free download on their official website. Julien-K has also teamed up on Chester Bennington's solo project, the band called Dead by Sunrise. Dead by Sunrise has since released their debut album Out of Ashes on October 13, 2009. The band was on hiatus ever since, and with Bennington's passing in 2017, its fate is currently unknown. During Projekt Revolution 2007, Bennington replaced lead singer Ryan Shuck for the Chicago date of the tour while Shuck attended his brother's wedding. Julien-K, mostly Amir, collaborated with Brandon Smith of The Anix for three singles, "ANTILIFE", "Your Lies Are Like Fire" including a live acoustic cover of "Where Is My Mind?" by Pixies. All of them appeared on The Anix's studio album REVENGE.
