The U2 360° Tour is an ongoing worldwide concert tour by the Irish rock band U2.[1] Launched in support of the group’s 2009 album No Line on the Horizon, the tour will visit stadiums from 2009 through 2010, whereas the previous two tours, the Elevation Tour and the Vertigo Tour, featured indoor arenas.[2] The U2 360° Tour is named after the 360-degree staging and audience configuration it uses for shows,[3] which U2 claims is “the first time a band has toured in stadiums with such a unique and original structure.”[4] In an era of declining CD sales, the tour is expected to be a major source of income for the band.[5] – wikipedia.org
