Notable for a distinctive sound, mixing hard rock with electronic music, Pendulum is developing to cover a wider range of genres. Pendulum was originally formed in 2002 in Australia by Rob Swire, Gareth McGrillen, and Paul Harding. Rob and Gareth also constitute the electro house duo Knife Party (the original Australian members). 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" (2005) 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" (2008) and "Immersion" (2010).
