The group consist of singer-songwriter Sian Evans, songwriter-producer Ron Mcelroy and drummer Mitchell Glover.

Their second album, Kokopelli—released in August 2003 on Moksha Recordings/Sony and named after a mythical Native American spirit—focused less on drum and bass beats and more on guitar riffs and darker-toned lyrics.

On 25 October 2011, fresh from the success of Sian Evans collaboration with DJ Fresh "Louder" which had reached number 1 in the UK Singles Chart in July, Kosheen confirmed an album release in May 2012, and a single, titled "Get a New One", on 13 February.

An announcement was made by the band on their official website that Independence would be released at the end of September 2012.

On 8 November 2013, Kosheen debuted a video for the song "Harder They Fall" as an introduction to their fifth studio album, Solitude.
