In June 2007, Bon Jovi released their tenth studio album, "Lost Highway". The album influences the band's rock sound with that of country music following the success of a country version of the band's 2006 single "Who Says You Can't Go Home", a duet with Jennifer Nettles. To promote the new album, Bon Jovi made several television appearances, including the 6th annual CMT Awards in Nashville, "American Idol", and MTV Unplugged, as well as playing at the Live Earth concert at Giants Stadium. They also performed ten promotional gigs in the U.S., Canada, the UK, and Japan. As part of the 'tour', Bon Jovi were the first group to perform at London's new O2 Arena (formerly the Millennium Dome) when it opened to the public on June 24, 2007. The 23,000-seater stadium sold out within 30 minutes of tickets being released.
