Context paragraphs:
Electrical Storm (song): "Electrical Storm" is a song by Irish rock band U2.  It was released as a single from their second compilation album, "The Best of 1990–2000", and was one of the two new songs recorded for that album (the other one being "The Hands That Built America").  The music video for the song prominently features drummer Larry Mullen Jr., as well as actress Samantha Morton.  The song was written by Bono and is about two lovers who are fighting and the tension between them; it relates this to a looming electrical storm.  U2 did not play the song live until 2 July 2009, when they performed it on the second concert of their U2 360° Tour in Barcelona.

Innocence + Experience Tour: The Innocence + Experience Tour (styled as iNNOCENCE + eXPERIENCE Tour) was a worldwide concert tour by rock band U2.  Staged in support of the band's 2014 album "Songs of Innocence", the tour visited arenas throughout 2015.  It was U2's first time playing arenas since 2005–2006 on their Vertigo Tour.  Comprising two legs and 76 concerts, the Innocence + Experience Tour began on 14 May 2015 in Vancouver, Canada.  It visited North America from May through July, and Europe from September through December.  Shows were predominantly booked in pairs for each market.

The Joshua Tree Tour 2017: The Joshua Tree Tour 2017 is an ongoing worldwide concert tour by rock band U2 commemorating the 30th anniversary of their 1987 album, "The Joshua Tree".  The tour is visiting stadiums in 2017 across four legs: North America from May to July and in September, Europe from July to August, and Latin America in October.  It began on 12 May 2017 in Vancouver, Canada.  The band intends to play "The Joshua Tree" in its entirety on each date of the tour, marking the first live performances of the song "Red Hill Mining Town".  It is the first time the group is touring in promotion of an album from their back catalogue, rather than a new release.  As part of the tour, U2 headlined the Bonnaroo Music Festival in Manchester, Tennessee, in June.

U2 360° Tour: The U2 360° Tour was a worldwide concert tour by rock band U2.  Launched in support of the group's 2009 album "No Line on the Horizon", the tour visited stadiums from 2009 through 2011.  The concerts featured the band playing "in the round" on a circular stage, allowing the audience to surround them on all sides.  To accommodate the stage configuration, a large four-legged structure nicknamed "The Claw" was built above the stage, with the sound system and a cylindrical, expanding video screen on top of it.  At 164 ft tall, it was the largest stage ever constructed.  U2 claimed that the tour would be "the first time a band has toured in stadiums with such a unique and original structure."

PopMart Tour: The PopMart Tour was a worldwide concert tour by rock band U2.  Launched in support of the group's 1997 album, "Pop", the tour's concerts were performed in stadia and parks in 1997 and 1998.  Much like the band's previous Zoo TV Tour, PopMart was elaborately staged.  Its lavish stage design had a 165 ft wide LED screen, a 100 ft -high golden arch, and a large mirror-ball lemon.  As with the Zoo TV tour, the band delivered an image and performance that were ironic and self-mocking, deviating from its earnest performances of the 1980s; the band performed in costumes that, along with the PopMart stage design, poked fun at the themes of consumerism and pop culture.

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.

Fez – Being Born: "Fez – Being Born" is a song by Irish rock band U2 and the eighth track on their 2009 album "No Line on the Horizon".  It was planned for the track to open the album, but "No Line on the Horizon" was chosen instead.  The song had several different titles during the recording sessions, including "Chromium Chords" and "Tripoli", and was the result of a fusion of two different songs during the recording sessions.

War Tour: The War Tour was a concert tour by the Irish rock band U2, which took place in 1982 and 1983 in support of the group's third album "War".  The tour took place in Western Europe, the United States, and Japan, with new material from "War" taking an increasing role as the tour progressed.  Venues were mostly halls, but some arenas were introduced later on.  U2's performances were very well received both critically and commercially, especially in the United States where U2 broke through to become a major act.  Scenes of lead singer Bono waving a white flag during the song "Sunday Bloody Sunday" became an emblematic image of this phase of U2's career.  It was their first tour as full-time headlining act and their first to be profitable.

Zoo TV Tour: The Zoo TV Tour (also written as ZooTV, ZOO TV or ZOOTV) was a worldwide concert tour by rock band U2.  Staged in support of their 1991 album "Achtung Baby", the tour visited arenas and stadiums from 1992 to 1993.  To mirror the new musical direction that the group took with "Achtung Baby", the tour was intended to deviate from their past and confound expectations of the band.  In contrast to U2's austere stage setups from previous tours, the Zoo TV Tour was an elaborately staged multimedia event.  It satirised television and media oversaturation by attempting to instill "sensory overload" in its audience.  To escape their reputation for being earnest and overly serious, U2 embraced a more lighthearted and self-deprecating image on tour.  Zoo TV and "Achtung Baby" were central to the group's 1990s reinvention.

Vertigo Tour: The Vertigo Tour was a worldwide concert tour by the Irish rock band U2.  Staged in support of the group's 2004 album "How to Dismantle an Atomic Bomb", the tour visited arenas and stadiums from 2005 through 2006.  The Vertigo Tour consisted of five legs that alternated between indoor arena shows in North America and outdoor stadium shows internationally.  Much like the previous Elevation Tour, the indoor portion of the Vertigo Tour featured a stripped-down, intimate stage design.  Protruding from the main stage was an ellipse-shaped catwalk that encapsulated a small number of fans.
