Robert Swire Thompson (born 5 November 1982) is an Australian record producer, singer-songwriter and keyboardist. Swire is best known as lead singer and producer of Australian electronic band Pendulum and is sometimes referred to by the stage name Anscenic. He is also one of the two members in electronic dance music group 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.
