Girls Aloud are a British-Irish pop girl group formed through the ITV talent show Popstars: The Rivals in 2002. The group's original line-up comprised Cheryl, Nadine Coyle, Sarah Harding, Nicola Roberts and Kimberley Walsh. They achieved immediate success with their debut single, "Sound of the Underground", which became the 2002 UK Christmas number one. Girls Aloud subsequently became one of the most commercially successful British girl group of the 21st century, achieving twenty consecutive top ten singles on the UK singles chart, including four number ones, and two number one albums. Throughout most of their career, Girls Aloud worked with the songwriting and production team Xenomania, led by Brian Higgins. Their music combined mainstream pop with elements of electronic music, rock and dance, frequently using unconventional song structures and abrupt shifts in style. The partnership produced songs including "Love Machine", "Biology", "Something Kinda Ooooh", "Call the Shots" and "The Promise", and attracted critical acclaim for its inventive approach to commercial pop.
