evidence: Given U2‘s reputation for pushing technical and creative boundaries with its live concerts, it seemed fitting that the band opened the anticipated Sphere in Las Vegas on Friday with its most ambitious and transportive live show ever: an electrifying live performance and visual odyssey that unfolds on Sphere’s enveloping 160,000-square-foot wraparound interior LED display. Built for an estimated $2.3 billion, Sphere is a big gamble by MSG mogul James Dolan and Sphere Entertainment Co. (which was formed in April to combine Sphere and MSG Networks) on the future of entertainment. At 336 feet tall and 516 feet wide, the venue is now the largest spherical structure in the world, housing the largest interior and exterior wraparound LED displays. Inside, the enveloping LED display supports a high resolution of 16K, meaning that it delivers images so lifelike that it may make you feel as though you’re no longer in a Las Vegas venue but transported into the visual content — something that U2 used to great effect during the two-hour show. Meanwhile, an all-new immersive sound system from Berlin-based Holoplot is configured with roughly 1,600 loudspeakers to deliver the experience to all of the seats in Sphere’s challenging design.
