Following Bono 's recuperation , U2 embarked on the Innocence Experience Tour in May 2015 , visiting arenas in North America and Europe from May through December . The group structured their concerts 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 . The stage spanned the length of the venue floor and comprised three sections : a rectangular main stage , a smaller circular B-stage , and a connecting walkway . The centerpiece of the set was a double-sided video screen that featured an interior catwalk , allowing the band members to perform amidst the video projections . U2 's sound system was moved to the venue ceilings and arranged in an oval array , in hopes of improving acoustics by evenly distributing sound throughout the arena . In total , the tour grossed US$ 152.2 million from 1.29 million tickets sold . 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
