Knife Party are an Australian electronic music duo consisting of Rob Swire and Gareth McGrillen, two members of the drum and bass band Pendulum.

The name is derived from the Deftones song "Knife Prty" featured on the 2000 album White Pony.

[5] Knife Party's first EP, 100% No Modern Talking, was released digitally through Warner Bros. Records on 12 December 2011.

[6] 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.

[citation needed] In May 2014 Swire stated that the debut Knife Party album was near completion and that they were in their final stages of finishing it.

[11] Knife Party's Rob Swire mentioned in a tweet that he was happy with the album leaking, but that he felt it made "months of arguments about release dates and watermarks pointless.

"[12] Evidence of a possible new EP made itself known during their performance at Ultra Music Festival 2015 where they debuted three new tracks: Parliament Funk, PLUR Police and Kraken ft. Tom Staar.

[14] At Kingsday Festival 2015 they premiered a brand new collaboration with Tom Morello of Rage Against the Machine.

[15] Official remixes by Brillz and Ephwurd were released shortly after as well as a Live version from the Ultra performance.

At a Life in Color event held in Manchester on 3 February 2018, they played out a remix of Pendulum's "Blood Sugar" that was released with the Pendulum's Reworks album launching 16 March and releasing in full on 29 June 2018.

[16] This collaboration was eventually titled "Harpoon" and released as part of the Pegboard Nerds' Full Hearts EP in July.
