Following the success of their debut single "Sound of the Underground", which spent four weeks at number one, the group has been successful in achieving a string of twenty consecutive top ten singles (including three more number ones) and two number one albums in the United Kingdom. All of their albums have been certified platinum, with their greatest hits album The Sound of Girls Aloud selling over one million copies. They have been nominated for five BRIT Awards, winning Best Single in 2009 for "The Promise". The group has sold ten million records worldwide.
Girls Aloud's collaborations with Brian Higgins and his songwriting and production team Xenomania have earned the group critical acclaim, due to an innovative approach to mainstream pop music. The group has become one of the few UK reality television acts to achieve continued success, amassing a fortune of £30 million by May 2010. Guinness World Records lists them as "Most Successful Reality TV Group" in the 2007 edition. They also hold the record for "Most Consecutive Top Ten Entries in the UK by a Female Group" in the 2008 edition.
The Out of Control Tour is Girls Aloud's fourth arena-based concert tour and their fifth tour overall. Thirty-two dates were announced for the arena tour. The tour started on 24 April 2009 in Manchester's MEN Arena, with the final show on 6 June 2009 in Newcastle's Metro Radio Arena. The group performed three nights at London's O2 Arena and two at Wembley Arena. In addition to their own dates, Girls Aloud opened for Coldplay's Viva la Vida Tour at Wembley Stadium on 18 and 19 September 2009. The tour's layout included various props, such as podiums, poles, and ramps, as well as an additional smaller stage in the middle of the arena. The show was broadcast on Sky1 in August 2009 and was later released on DVD and Blu-Ray.
Chemistry is the third studio album by British all-female pop groupGirls Aloud. Recording sessions took place in 2005, following Girls Aloud's first tour What Will the Neighbours Say? Live. It was released by Polydor Records on 5 December 2005 in the United Kingdom. The album was entirely produced by Xenomania. The album was described as "a concept album which relates to the girls and what it's like to be a twentysomething girl in London". The Guardian said that the album's "lyrics sound like Blur's Parklife rewritten by the editorial staff of Heat magazine" and "holds a distinctly ambiguous mirror up to noughties celebrity". Girls Aloud came under fire for the album's allegedly "dirty lyrics".
Despite being the group's lowest charting album to date, Chemistry was certified platinum in the UK and Ireland and earned the group critical acclaim. In 2008, Slant Magazine said that "Chemistry is probably still their crowning glory". It spawned four top ten singles - "Long Hot Summer", "Biology" (called "the best pop single of the last decade" by Peter Cashmore of The Guardian), their cover of Dee C. Lee's "See the Day", and lastly, "Whole Lotta History".
