is inarguably the biggest show Baltimore will have all year. The superlative applies not only because no other headliner approaches the band's supernova-sized star power, but also literally: The show, part of the band's 360 tour, is of unprecedented size and scope. Its centerpiece is a circular, four-legged stage that can support nearly 200 tons and allows for the namesake 360-degree view. It carries a video screen that, when open, is 14,000 square feet. The production is so intimidatingly large it requires hundreds of staffers to work over several days to build and then dismantle the stage. Craig Evans, the tour director, says the tour, already the most financially remunerative of all time, has altered the way stadium concerts are presented.
