Pendulum is an Australian/British drum and bass group founded in 2002, and has been active since. Pendulum originaly formed in the Australian city of Perth, Western Australia by Rob Swire, Gareth McGrillen, and Paul Harding. Rob and Gareth also constitute the electro house duo Knife Party (the original Australian members). The group was notable for a distinctive sound, mixing hard rock with electronic music, and developing to cover a wider range of genres. Swire and McGrillen were members of the metal band known as Xygen. After hearing Konflict's "Messiah" at a club, they were inspired to enter into the Drum & Bass genre. They founded Pendulum with Paul Harding, who was a veteran DJ in the Drum & Bass scene. In 2003 the band relocated to the United Kingdom. While Hold Your Colour holds true to the Drum & Bass genre, Pendulum have since experimented with mixing other genres into their work, as can be heard on In Silico and Immersion. In August 2013, Swire announced that a new album may be released "some time next year 2014".
