McGrillen and Swire first met as members of metal band Xygen before hearing Konflict‘s "Messiah" at a club and vowing to enter the Drum and Bass scene. After recruiting DJ Paul Harding, they created the drum and bass rock fusion band Pendulum in 2002 and enjoyed a rise to fame after their 2005 release Hold Your Colour. By 2007 they re-released the album with the massive drum and bass scene hit "Blood Sugar" and began work on their next album In Silico, which brought considerable mainstream success. They followed up with a third album in 2010, Immersion, which was also well received in the mainstream. 
On 25 May 2011, Swire released a short preview on SoundCloud entitled "Not Pendulum". On 5 August 2011, McGrillen and Swire made their first public appearance as Knife Party at Space, a nightclub located on the island of Ibiza in the Mediterranean Sea. The duo are named after a song on the Deftones album White Pony.
2011: 100% No Modern Talking 
Knife Party's first EP, 100% No Modern Talking, was released digitally through Pendulum's imprint record label EarStorm. It was released as free download from their official website, Soundcloud and Facebook, as well as being available for purchase on Beatport and iTunes on 12 December 2011. The EP originally was to feature "Back to the Z-List" but was replaced with "Destroy Them with Lazers" as the duo had decided to abandon the track. A tweet in December 2011 suggested the possibility of a remix EP in the future. The EP title refers to the lack of "Modern Talking", a wavetable in the software synthesiser NI Massive commonly used to create "talking" basslines.
2012: Rage Valley 
Their second EP, Rage Valley, was released digitally through EarStorm and Big Beat. Rob tweeted a screenshot taken on his PC showing three of the four final Rage Valley tracks, captioning the photo "3 down, 1 to go", referring to the mastering of the final track "Sleaze". The title track "Rage Valley" was originally named "Fuck Em"  but the title was changed "for secret shady reasons you will never know" according to Rob. "Sleaze" was also re-titled, the original being called "Until They Kick Us Out". Originally Rage Valley was set to be released before the end of April 2012, but due to multiple setbacks the release was delayed for four weeks. It was made available for purchase on Beatport and iTunes on 27 May 2012.
2013: Haunted House 
Their third EP Haunted House, was released on 6 May 2013 digitally through EarStorm and Big Beat. A last minute change was made to the EP and where "Baghdad" was replaced with "Internet Friends" (VIP Mix). Rob also announced the approximate release date for the new EP in a tweet, the week of 22 April, with iTunes on 29 April. However, Rob later announced the final release date will be May 6th due to issues beyond his control. The EP was leaked on 29 April, and later uploaded in its entirety on Knife Party's YouTube channel on May 5th as well as a trailer video for the EP. The EP entered into the iTunes Top 10 Albums Chart and peaked at 3rd place. It also hit number 1 Electro House Album on Beatport.
