Chemistry is the third studio album by British all-female pop group Girls Aloud. It was released in the United Kingdom on 5 December 2005 by Polydor Records. After the success of What Will the Neighbours Say?, the album was again entirely produced by Brian Higgins and his production team Xenomania. Chemistry is a "loose concept" album which details celebrity lifestyle and "what it's like to be a twentysomething girl in London." A number of the songs notably avoid the typical verse-chorus form of pop music, instead making use of unusual structures. Chemistry was widely acclaimed by a number of contemporary music critics upon its release. Despite a relatively low chart position (peaking at 11, it is the lowest charting release by the group), the album yielded four top ten singles and was certified platinum in the United Kingdom and Ireland. The album was followed by the Chemistry Tour, Girls Aloud's first concert tour to reach arenas. Chemistry explores a more innovative approach to pop music, straying from the typical verse-chorus form present in most songs, drawing inspiration from a lot of genres like ska, swing pop, power pop, new wave, bossa nova, new prog and rap. Chemistry appeared at number 13 on Stylus Magazine's Top 50 Albums of 2005 and number 35 on Observer Music Monthly's top 100 albums of 2005 list. In 2008, Slant Magazine said that "Chemistry is probably still their crowning glory". User-contributed text is available under the Creative Commons By-SA License; a
