X is the tenth studio album by Kylie Minogue, released on 21 November 2007 by Parlophone. It is her first release since the greatest hits compilation Ultimate Kylie (2004), and her first studio album since Body Language (2003). Work on the album began following Minogue’s gradual recovery from breast cancer and subsequent radiotherapy treatment. Her cancer, which was diagnosed in May 2005, resulted in the postponement of Showgirl: The Greatest Hits Tour midway through its run. Minogue resumed the tour in late 2006, in the midst of recording X, and was completed later in the following year. The album introduced new American and European producers including Bloodshy & Avant, Guy Chambers, Calvin Harris and Freemasons.

X released its first single “2 Hearts“. Written by Jim Eliot and Mima Stilwell. The song was a commercial success, peaking inside the top ten in countries including Australia and Spain (peaking at number one in both territories), Italy, Ukraine, Sweden and the United Kingdom.

Two singles release on 16 and 17 February respectively; “Wow” was released in Australia, Europe and the United States, while “In My Arms” was released in Europe.

“All I See” and “The One” were released as digital singles, the first to promote the album in the United States and the latter released in Europe.

Despite never having been released as a single, “Speakerphone” managed to chart on the Canadian Hot 100 at number eighty-seven based on high downloads from the album. In August 2009, Minogue held a competition for fans to create a music video for “Speakerphone”. The winner was an animation made by Hungarian animator Rudolf Pap, whose video was shown at the Hollywood Bowl on 4 October 2009 prior to Minogue’s concert.

X was promoted by the KylieX2008 tour where she traveled around Europe, Oceania, South America, Asia and South Africa. The tour received favorable reviews from critics and was a commercial success, making it Minogue’s most expensive tour at the time.  The album was nominated for a BRIT Award for International Album in 2008, as well as a Grammy Award for Best Electronic/Dance Album in 2009, Minogue’s fifth Grammy Award nomination.
