Pendulum乐队以沉重有冲击力的电子节拍和将多种音乐风格杂糅而著称，因此，有人将他们的音乐风格简单的定义为“Drum & Bass”是不准确的，Pendulum音乐的多样性是很难用一个词来定义的。由于Pendulum的两名成员深受Led Zeppelin和Tool等摇滚乐团的影响，因此他们的音乐当中摇滚乐和工业音乐的比重是很大的。把经典的摇滚乐和工业音乐片断融入到时尚的电音当中，Pendulum音乐的接受面还是很广的，再加上大公司更具水准的制作能力，《In Silico》听起来要比他们的处子作《Hold Your Colour》有了明显的进步
Far and away one of the most popular drum'n'bass acts of the early 21st century, Pendulum is an Australian group based in the United Kingdom who rose up from the underground quickly with a diverse style of drum'n'bass that is anything but generic. Formed in Perth in 2002, the group was originally comprised of producers Rob Swire and Gareth McGrillen in tandem with Paul "El Hornet" Harding, a local DJ. In 2003 one of their initial releases, "Vault," became a sensation amid the drum'n'bass community, benefitting greatly from high-profile placement at the beginning of J Majik's FabricLive (2003) mix album. The track was also licensed for placement on several other CDs, including Adam F and DJ Fresh's Breakbeat Kaos (2003) mix album for Ministry of Sound. Other early productions such as "Spiral" (2003) and "Another Planet" (2004) — released by Adam F and DJ Fresh on their Breakbeat Kaos label — were also well-received in the drum'n'bass community. In 2005 Pendulum made their full-length album debut, Hold Your Colour, featuring the singles "Tarantula" and "Slam." Also in 2005 the group scored its biggest hit to date with a remix of the Prodigy classic "Voodoo People," which broke into the Top 20 of the U.K. singles chart. All of this success in 2005 culminated with an Essential Mix for BBC Radio 1 late in the year. Following a couple one-off singles — "Painkiller" (2006; featuring the Freestylers) and "Blood Sugar" (2007) — Pendulum signed to Warner Music U.K. and made their major-label debut with "Granite" (2007), a Top 30 hit. "Propane Nightmares" (2008), their second release on Warner, was an even bigger hit, breaking into the Top 20 and setting the stage for their second full-length album, In Silico (2008).
