Kevin Mazur/WireImage Bono of U2 performs during the U2 360 Tour at New Meadowlands Stadium on July 20, 2011 in East Rutherford, New Jersey. A decade ago, U2 toured the globe with groundbreaking technology and thirty years of bulletproof rock anthems on the U2 360° Tour. After oscillating between arenas and stadiums throughout the 2000s, the Irish quartet spent 2009-11 exclusively playing stadiums in Europe, North and South America, Africa, and Australia. Along the way, exactly 10 years ago today, on April 13, 2011, the U2 360° Tour played the third of a three-show stint at Estadio do Morumbi in Sao Paolo, Brazil. It was the biggest engagement of the entire tour and propelled the run’s so-far gross to $580 million, making it the then-highest-grossing tour in Billboard Boxscore history. (The record has since been broken by Ed Sheeran. More on that below).
