City Boy was an English rock band, formed in Birmingham in 1975. Known for their complex vocal arrangements and heavy keyboard orchestration, they combined elements of progressive rock with pop sensibilities. The band's most significant work is arguably their 1978 hit "5.7.0.5.," which reached the Top 10 in the UK charts. Despite a relatively short-lived success, City Boy's intricate musicianship and innovative blending of genres have left a lasting mark on the landscape of classic rock.
