Backstage at the U2 360 Tour

Opening night of the U2 360 U.S. stadium tour was an amazing experience. More than 90,000 people descended on Chicago’s Soldier Field, each one ready for an incredible spectacle—and they didn’t leave disappointed. The concert was full of everything you’d want from a U2 show: visual extravagance, brash music and crystal-clear sound. In fact, the show was such a big story that I actually wrote two stories for Pro Sound News: one about the Front-of-House mix (sound for the audience) and one on the monitor mixes (sound for the band). Below are a few images from the day that never saw print.

A whole world exists under the stage; there's everything from guitar and bass workshops to changing- and bathrooms for the band, to the monitor mix area (shown), where I interviewed the engineers who create the mixes that the band hears while performing.

Edge's Guitars

Some of the 40-plus guitars ready each night for the Edge--two for each song, with one reserved as a backup.

Adam Clayton goes through about six basses in the course of a show, so there's about a dozen at the ready for him.

With a show as complicated as U2 360, the crew always needs to know what's next, so there's both songs and notes on the set list.
