A Certain Ratio are a Post-punk band formed in 1977 in Manchester, England. While originally part of the punk rock movement, they soon added funk and dance elements to their sound. They are sometimes referred to as "post punk funk". The band's name is taken from the lyrics of Brian Eno's song "The True Wheel" (from the album Taking Tiger Mountain (By Strategy)
The group's longest serving original members are been Martin Moscrop (guitar, trumpet) and Jeremy Kerr (bass, vocals). Another current member, Donald Johnson (drums, vocals), joined after the first drummerless single. Two of ther original members have left the band - Simon Topping (left in 1983 for Quando Quango and, later, T-Coy), plus guitarist Peter Terrell, who left in 1982. Keyboardist Andy Connell who joined in 1982 left to form Swing Out Sister in 1985.
A Certain Ratio's first recording contract was with Factory Records in 1979. They released The Graveyard and The Ballroom only on cassette in 1980. This led them to put out another experimental album, To Each..., released in 1981, was the band's official debut album. With growing popularity and success, the band signed with A&M Records in 1987, and Good Together was released in 1989. The album failed to produce a hit, leading to the band's departure from the label. In the early 1990s, they signed with Rob's Records, owned by New Order manager Rob Gretton.
The band's exploration of rhythm fusing funk, disco, punk and Latin has had a resurgence in the last few years and their influence can be heard in bands such as The Rapture and LCD Soundsystem. In 2002 Soul Jazz Records started a program of reissues of ACR's albums and difficult to find tracks. Further re-issues and a live recording from 1980 have also been made available on the LTM label.
Although the band does not play full time, they continue writing, recording, and performing. A Certain Ratio performed in the US for the first time since 1985 on November 16, 2008, headlining the Part Time Punks Festival at The Echo in Los Angeles, California.
They were managed by Tony Wilson. They are featured in the film 24 Hour Party People where Tony Wilson (played by Steve Coogan) calls them "Joy Division but better dressed." Martin Moscrop was Musical Supervisor of 24 Hour Party People.
Simon Topping appeared on stage with Joy Division - filling in for an indisposed Ian Curtis - at a concert in Bury's Derby Hall on April 8 1980 which ended in a riot (featured in the Anton Corbijn film Control). This concert took place a few weeks before Curtis' suicide.
