For a few moments, the MSG Sphere in Las Vegas lit up, causing time to stand still, jaws to drop, and people to marvel at the marvel created by the marriage of vision, ambition, and skill. It was as if an otherworldly element had taken up residence on our planer, displaying cascading red and yellow lights with the greeting “Hello World” on the LED screen.

The $2.3 billion Madison Square Garden Sphere, designed by Populous, will feature the world’s largest and highest LED resolution screen, measuring 19,000 x 13,500 pixels.

The world’s largest spherical structure is set to open in September, with a fitting start: the world’s best-selling rock band U2 will open its Las Vegas residency on September 29 and 30, performing the first shows. A video of the incredible 366-foot-high and 516-foot-wide structure was revealed on Twitter, with user Michel rightfully dubbing it the most incredible building ever, ‘First animation of the MSG Sphere this morning.

This will be the coolest building on the planet.’

The massive and costly mother of all entertainment venues will have 18,000 seats and an HD screen the size of three football fields. Tests were conducted in preparation for the 4th of July, when it will be fully illuminated for the first time.”The idea behind U2 is always to make the worst seat in the house the best seat in the house,” Bono said. This changes the entire dynamic.”

“Most music venues are sports venues,” he adds, “rather than theatres.” They’re stadiums and arenas. They’re designed for sports. They’re not made for music, and they’re not made for art. As a result, this structure was designed to provide immersive experiences in cinema and performance.”

On July 4th, the MSG Sphere was activated to give an even more hypnotic demonstration of its capabilities.
