Mansun were formed in chester in 1995 by vocalist/ rhythm guitarist Paul Draper, lead guitarist/ backing vocalist Dominic Chad, bassist Stove King and drummer Andie Rathbone. They were known for regularly changing their sound (and attire), often between each EP release - liberally mixing beatrock, prog, psychedelia, pop and 80s noir influences - along with being a fearsome live act who drastically rearranged their songs for the stage.

They came to prominence in the mid-nineties British indie/ guitar-rock resurgence, despite pursuing their own path away from any of the emerging scenes. Their first album Attack of the Grey Lantern could easily have been lost amidst the wave of new music in the British (britpop) scene at that time if it had not been for the majestic Wide Open Space. The single charted at number 15 in the UK. The album then went on to reach no. 1 in the UK charts. Many of the tracks from the album and the associated EP's formed part of a grand concept piece. The band created a twisted town inhabited by bizarre characters such as "Dark Mavis", "Stripper Vicar", "Flourella" and "Egg-Shaped Fred".

Between their 1st and 2nd album they released the Closed For Business EP which departed from the themes that had run through all Mansun's previous releases, while musically very similar to the tracks from Attack of the Grey Lantern.

The band's second album Six was a radical departure from the first album. The tracks segued into each other creating two musical sections which were separated by an "intermission". Musically, the songs were far more produced in sound. The album artwork was also very complex containing many references to the cult (and often surreal) 60's TV show "The Prisoner". This perfectly suited the music which had the feeling of a nonsensical prog extravaganza. The artwork together with the way that the complex structure of the songs/time signatures blended into each other gave the impression of a very ambitious progressive rock concept album, though lyrically there is little to suggest that there is a central theme to the album. While generally critically appreciated, Six was not a huge commercial success, though the album did reach no. 6 in the UK album charts.

For their third album, Little Kix, Mansun again changed direction. This time the songs were slickly produced (over-produced in some senses) with strong pop sensibility. The album was obviously an attempt by the band to produce an album with more maturity, but was perhaps too polished. Little Kix reached no. 12 in the UK charts.

Mansun disbanded in May 2003. This was a culmination of band tensions which had seen one of the original members leave (Stove King). Disappointed by the poor reception of their 3rd album, the band folded with little fanfare of their passing.

Due to pressure from their fans, EMI released the posthumous "4th album", Kleptomania, which was a three CD set containing rough recordings of tracks slated to be on the unfinished 4th album, b-sides and rarities.
