More than seven months after rumors circulated that U2 would perform the first-ever concerts at Las Vegas’ MSG Sphere, the Irish rockers officially announced on Super Bowl Sunday that they will stage shows dedicated to their 1991 LP Achtung Baby to launch the city’s massive new globe-shaped venue.

Bono and company — who have their sorta-new album Songs of Surrender arriving in March — previously teased the worst-kept secret in Sin City prior to the Super Bowl, posting an image of a newborn baby within the newly constructed MSG Sphere on a website not-so-subtly called U2xsphere.com. The official announcement came Sunday, with a mysterious UFO-themed ad for the ‘U2:UV Achtung Baby Live At The Sphere’ shows this fall.
