Pendulum is an Australian/British drum and bass group formed in 2002 in Perth, Western Australia by Rob Swire, Gareth Mcgrillen, and Paul Harding. They were inspired to enter drum & bass after hearing Konflict's "Messiah" and developed a distinctive sound mixing hard rock with electronic music. While their early works stuck to drum & bass, later albums like In Silico and Immersion experimented with other genres. Although Pendulum has split up, Rob Swire and Gareth Mcgrillen continue to have success with their electronic dance music duo Knife Party.
