U2's  360 world tour doesn't hit the U.S. until September, but you can get a sneak peak at the action now. 

See the tour come together as you see the construction of the set, plus comments from the band's manager and tour producer. Plus see Bono and the boys' first reaction to the massive set. All we can say is Wow!  It is clearly one of the largest productions ever staged. Moving it from city to city is going to be a Herculean fete.

The tour opened June 30 in Barcelona and moves through Europe, finally touching down in the U.S. on Sept. 12 at Chicago's Soldier Field. At the opening, the band dedicated "Angel of Harlem" to Michael Jackson before segueing into "Man in the Mirror."

The Irish band is touring behind its latest album, "No Line on the Horizon."
