The band originally formed in 2000 and released three studio albums, All Rise (2001), One Love (2002) and Guilty (2003) that all peaked at number one in the United Kingdom alongside releasing sixteen singles, over a four-year period.

The group also worked alongside artists such as Stevie Wonder, Elton John and Lil Kim.

However, in 2005 they confirmed that they would be splitting due to wanting to pursue solo careers.

In May 2011, they represented the United Kingdom at Eurovision with the song "I Can", finishing 11th.

In 2022, Blue returned with singles "Haven't Found You Yet" and a cover of "Dance with Me", both from their sixth studio album Heart & Soul which was released on 28 October 2022.
