The Mercury Prize, formerly called the Mercury Music Prize and currently known as the Barclaycard Mercury Prize for sponsorship reasons, is an annual music prize awarded for the best album from the United Kingdom and Ireland. It was established by the British Phonographic Industry and British Association of Record Dealers in 1992 as an alternative to the Brit Awards. The prize was originally sponsored by Mercury Communications, a brand owned by Cable & Wireless, from which the prize gets its name. It was later sponsored by Technics, from 1998 to 2001, Panasonic, in 2002 and 2003, and the Nationwide Building Society, from 2004 to 2008. Barclaycard became the Prize's current sponsor in March 2009.

Nominations are chosen by a panel of musicians, music executives, journalists and other figures in the music industry in the UK and Ireland. Presentation of the award usually takes place in September after the nominations are announced in July. It is often observed that bands whose albums are nominated, or win the prize, experience a large increase in album sales, particularly for lesser known nominees. However, despite being regarded by many as highly prestigious, it has been suggested that having an album nominated for or winning the Mercury Prize could be a curse on a career in music.

Amy Jade Winehouse (14 September 1983 – 23 July 2011) was an English singer and songwriter known for her powerful deep contralto vocals and her eclectic mix of musical genres including R&B, soul and jazz. Winehouse's 2003 debut album, Frank, was critically successful in the UK and was nominated for the Mercury Prize. Her 2006 follow-up album, Back to Black, led to six Grammy Award nominations and five wins, tying the then record for the most wins by a female artist in a single night, and made Winehouse the first British female to win five Grammys, including three of the "Big Four": Best New Artist, Record of the Year and Song of the Year.

In 2007 she won a Brit Award for Best British Female Artist; she had also been nominated for Best British Album. She won the Ivor Novello Award three times: once in 2004 for Best Contemporary Song (musically and lyrically) for "Stronger Than Me", once in 2007 for Best Contemporary Song for "Rehab", and once in 2008 for Best Song Musically and Lyrically for "Love Is a Losing Game".

Polly Jean Harvey (born 9 October 1969) is an English musician, singer-songwriter, composer and occasional artist. Primarily known as a vocalist and guitarist, she is also proficient with a wide range of instruments including piano, organ, bass, saxophone, harmonica, and most recently, the autoharp.

Harvey began her career in 1988 when she joined local band Automatic Dlamini, whose vocalist and saxophone player, John Parish, would become her long-term collaborator. In 1991, she formed an eponymous trio and subsequently began her professional career. The trio released two studio albums, Dry (1992) and Rid of Me (1993) before disbanding, after which Harvey continued as a solo artist. Since 1995, she has released a further six studio albums with collaborations from various musicians including John Parish, former bandmate Rob Ellis, Mick Harvey, and Eric Drew Feldman and has also worked extensively with record producer Flood.

Among the accolades she has received are the 2001 and 2011 Mercury Prize for Stories from the City, Stories from the Sea (2000) and Let England Shake (2011) respectively—the only artist to have been awarded the prize twice—eight BRIT Award nominations, six Grammy Award nominations and two further Mercury Prize nominations. Rolling Stone awarded her 1992's Best New Artist and Best Singer Songwriter and 1995's Artist of the Year, and listed Rid of Me and To Bring You My Love (1995) on its 500 Greatest Albums of All Time list. In 2011, she was awarded for Outstanding Contribution To Music at the NME Awards.
