Formation and debut album (2012–2017) Tilling began developing what would become Circu5 in 2012, with the intention of creating music independently and on his own terms. The self-titled debut album was released in 2017. The record featured contributions from several guest musicians, including
Dave Gregory of
XTC,
Big Big Train and Tin Spirits. The debut album introduced Circu5’s central concept: the story of "
Grady", a character raised as a
psychopath within a covert organisation known as Circu5.
Hiatus, transition to full band and second album (2018–2025) In 2018, Tilling joined TC&I, the band of XTC members
Colin Moulding and
Terry Chambers, in which he met TC&I bandmate and future Circu5 drummer Lee Moulding (Colin’s son). When TC&I disbanded, Tilling became the lead singer and guitarist for EXTC, another XTC-related project featuring Chambers. On leaving EXTC in late 2022, Tilling refocused on Circu5. The band completed their second album,
Clockwork Tulpa, which was released in March 2025. In June 2025, guitarist and vocalist Paul New joined the line-up, making Circu5 a four-piece band consisting of Tilling, New, Mark Kilminster (bass, vocals) and Lee Moulding (drums, vocals). == Concept ==
