U2's previous tour, the U2 360° Tour, visited stadiums in Europe, North America, Asia, Oceania, Africa and South America from 2009 to 2011 and comprised 110 shows.

In 2018, U2 reprised the tour's autobiographical narrative and stage setup for its sequel, the Experience + Innocence Tour. The final date of the tour, one of two Paris shows rescheduled due to the 13 November 2015 attacks in the city, was filmed for the video Innocence + Experience: Live in Paris and broadcast on the American television network HBO.

In total, the tour grossed US$152.2 million from 1.29 million attendees. According to Billboard, the North American leg of the tour grossed US$76.2 million from 36 sold-out concerts. The Innocence + Experience Tour was well received by critics. For the tour, U2's sound system was moved to the venue ceilings and arranged in an oval in hopes of improving acoustics by evenly distributing sound throughout the arena. A 96-foot-long (29 m) double-sided video screen was suspended above and parallel to the walkway the structure featured an interior catwalk between the video screens, allowing the band members to perform amidst the video projections. The stage spanned the length of the venue floor and comprised three sections: a rectangular segment representing 'innocence' a smaller circular B-stage representing 'experience' and a connecting walkway to represent the transition between the two themes. Shows were predominantly booked in pairs for each market.Ĭoncerts were structured around a loose autobiographical narrative of 'innocence' passing into 'experience', with a fixed set of songs for the first half of each show and a varying second half, separated by an intermission-a first for U2 concerts. It visited North America from May through July, and Europe from September through December.

Comprising two legs and 76 concerts, the Innocence + Experience Tour began on in Vancouver, Canada.

It was U2's first time playing arenas since 2005–2006 on their Vertigo Tour. Staged in support of the band's 2014 album Songs of Innocence, the tour visited arenas throughout 2015. The Innocence + Experience Tour (styled as iNNOCENCE + eXPERIENCE Tour) was a worldwide concert tour by rock band U2.
