What number of studio album release did U2's Innocence + Experience Tour support?
Songs of Innocence (U2 album) Songs of Innocence is the thirteenth studio album by Irish rock band U2. Released on 9 September 2014, it was produced by Danger Mouse, with additional production from Paul Epworth, Ryan Tedder, Declan Gaffney, and Flood. The album was announced at an Apple Inc. product launch event and released the same day to all iTunes Store customers at no cost. It was exclusive to iTunes, iTunes Radio, and Beats Music until 13 October 2014, when it received a physical release on Island and Interscope Records. The digital release made the record available to over 500 million iTunes customers, for what Apple CEO Tim Cook marketed as "the largest album release of all time".
Elevation Tour The Elevation Tour was a worldwide concert tour by the Irish rock band U2. Launched in support of the group's 2000 album "All That You Can't Leave Behind", the tour visited arenas in 2001. After the band's previous two extravagant stadium tours, Zoo TV and PopMart, the Elevation Tour returned the band to indoor arenas with a much more stripped-down, intimate stage design. A heart-shaped B-stage extended from the main stage, while encapsulating many of the fans.
