Inside U2's Boundary-Breaking Immersive Vegas Show

WIRED: When U2 launched its Zoo TV tour in 1991, it revolutionized live music. Over the course of 157 shows, the tour—which was in support of their album Achtung Baby—was almost an embarrassment of overwhelming sights and sounds, with cutting-edge visuals (for the time), a lighting system that was encased partially in Soviet-era Trabant cars, and a leather-clad Bono at times portraying a character named MacPhisto. It was a big swing for the group—and it worked. The group reportedly took in more than $151 million in ticket sales, and the tour is still hailed as one of the most artistically successful of all time.
