U2 360° Tour (17 June 2011)

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. It was named for a stage configuration that allowed the audience to almost completely surround the stage. To accommodate this, a massive four-legged supporting rig, nicknamed "The Claw", was built above the stage, with the sound system and a cylindrical, expanding video screen atop it. The tour was claimed by U2 to be "the first time a band has toured in stadiums with such a unique and original structure."
