Colin Ivor Moulding is an English bassist, singer, and songwriter who was one of the core members of the rock band XTC. Moulding wrote their first three charting UK singles: "Life Begins at the Hop" (1979), "Making Plans for Nigel" (1979) and "Generals and Majors" (1980).

XTC were an English rock band formed in Swindon in 1972. Fronted by songwriters Andy Partridge and Colin Moulding, the band gained popularity during the rise of punk and new wave in the 1970s, later playing in a variety of styles that ranged from angular guitar riffs to elaborately arranged pop. Partly because the group did not fit into contemporary trends, they achieved only sporadic commercial success in the UK and US, but attracted a considerable cult following. They have since been recognised for their influence on post-punk, Britpop and later power pop acts.
