According to the Lincoln Journal Star, 15,000 fans attended METALLICA's September 6 concert at the Pinnacle Bank Arena in Lincoln, Nebraska, which set a record as the heaviest ever, with a "dynamic weight" of up to 240,000 pounds.
The five-year-old building's roof held up under the weight which hung from the arena's rigging grid and steel beams attached to the major trusses.
That was even more impressive because the show was performed on a stage in the center of the arena, with all the production gear, sound and lighting, hung in a circle in the middle of the building.
The setup required 158 rigging points and took less than five hours to complete — far less than the nearly 10 hours it took to get everything ready at Minneapolis's Target Center two days earlier.
"The structural design was developed for doing concerts," Pinnacle Bank Arena manager Tom Lorenz told the Lincoln Journal Star. "That was a desire we had during the design phase, about having the structural capacity to hang the biggest shows and to have the building really fitted for concerts. The architects, engineers and builders gave us that. That gives us a leg up. This is unique. Not every building will be able to put up all of [METALLICA's] show. We were able to do it well and do it fast."
According to Pollstar Boxoffice, METALLICA's average gross over the past 36 months was $3.2 million, with an average of 32,313 tickets sold per show.
Touring in support of its latest album, "Hardwired… To Self-Destruct", that arrived in November 2016, METALLICA launched the world tour in Latin America a month before the disc's release. In early 2017, prior to the North American stadium tour, the band made festival appearances and headlined concerts at venues in Asia, Europe and Latin America.
Although METALLICA played U.S. stadiums last summer, the band was mostly indoors for the first leg of its European tour last fall.
