This actually the electro house/dubstep sided project of two guys from Pendulum (Rob Swire and Gareth McGrillen).
Knife party was founded back in 2011 and since then they remixed a couple of songs from some very well known artists such as Porter Robinson and Swedish House Mafia.
Their debut EP is called 100% No Modern Talking, which was released on 12/12/2011 as a free download and I got to tell you peeps, the EP is HUGE, you may surely want to check it out.
On 12/04/2012, the Australian duo announced their new EP on facebook. "2nd Knife Party EP will be out by the end of the month. Tracklist: Fuck Em, Centipede, Sleaze, Bonfire. EP is called.......RAGE VALLEY." but they missed the deadline. Shorty after, on 10/5/2012 they aplogised for the delay and promised the fans that the EP is going to be launched this month.
