Robert Swire-Thompson (born 5 November 1982) is an Australian record producer, singer-songwriter, guitarist, keyboardist and DJ. Swire is best known as the lead singer and producer of Australian drum and bass/electronic rock band Pendulum, and as the producer and DJ of the electronic dance music duo, Knife Party. Originally from Perth, Western Australia, he relocated to the United Kingdom in 2003 with fellow Pendulum co-founders Gareth McGrillen and Paul "El Hornet" Harding. Swire has since fulfilled a broad spectrum of roles as a member of Pendulum, ranging from song writing to singing while performing live with an unusual guitar-like MIDI controller – Starr Labs' Ztar Z6S-XPA. Swire can also play guitar, bass, keyboards and percussion. He is sometimes referred to by the stage name Anscenic.
