Displaying the kind of hubris that only a 23-year-old can muster, Scotland's Calvin Harris launched his career with the cheekily titled 2007 album I Created Disco. The title may have been slightly off-base (newsflash: Diddy didn't invent the remix, either), but Harris' LCD Soundsystem-inspired electro-funk was still punchy enough to catch the attention of Kylie Minogue, who enlisted him to co-write and produce two songs on her 2007 album, X. In 2008, Harris officially broke out of the electro-pop underground with "Dance Wiv Me," a collaboration with Dizzee Rascal that debuted at No. 1 on the U.K. pop charts. Harris' sophomore album, Ready for the Weekend, appeared in 2009. Like his debut, it's carefree and eager to please, but it boasts polished-up production skills and a range that takes in '80s funk, French house, trance-infused Euro-pop and even a smidgen of rock 'n' roll.
