Australia's biggest selling dance act and one of the most popular drum'n'bass acts of the early 21st century, Pendulum are an Australian group based in the United Kingdom. Formed in Perth in 2002, the group was originally comprised of producers Rob Swire and Gareth McGrillen, who worked in tandem with a local DJ named Paul "El Hornet" Harding. One of the team's initial releases, "Vault," became a sensation amid the drum'n'bass community in 2003, benefiting greatly from its high-profile placement at the beginning of J Majik's FabricLive mix album. In 2005, Pendulum made their full-length album debut, Hold Your Colour, featuring the singles "Tarantula" and "Slam."
Pendulum signed to Warner Music U.K. and made their major-label debut with 2007's "Granite," a Top 30 hit. Their second full-length album, In Silico (2008), spawned four singles, including U.K. Top Ten hit "Propane Nightmares". In Silico went on to reach platinum status in the U.K., as well as just missing out on the U.K. number one album chart spot. Their third album, Immersion, was released in 2010, and shot straight to the top of the U.K. albums chart. It featured collaborations with the Prodigy's Liam Howlett, Porcupine Tree's Steven Wilson, and Swedish metallers In Flames. In support of the album, Pendulum embarked on a world tour, playing two sold-out shows at London's Wembley Arena and headline slots at some of the U.K.'s largest festivals.
At the end of 2011, Pendulum took a break from live performing, with Rob Swire and Gareth McGrillen focusing their energy on their side project, Knife Party. In 2018, Pendulum returned from a seven-year hiatus, with Rob Swire, Gareth McGrillen and Paul Harding currently touring as Pendulum - Trinity.
