U2 are back. They’ve unveiled a new song – 'Atomic City'- and are now days away from only their second-ever residency: U2 UV: Achtung Baby at the purpose-built MSG Sphere in Las Vegas, a venue built specifically for live performance and the Arts, reported to have cost €2.3 billion.
It is reputed to have 1.2 million LEDs, that will form the biggest screen on the planet. Plus “There are no speakers” says Bono “the entire building is a speaker, so wherever you are, you have perfect sound.”
