U2 are set to extend their residency at the new Sphere venue in Las Vegas, according to reports.Held at the newly launched venue in Nevada, the Irish rock veterans became the first artist to perform at the Sphere and are currently underway with their residency which sees them perform some ‘Achtung Baby’ deep cuts for the first time in 30 years along with other classic hits.The live shows – titled ‘U2:UV Achtung Baby Live At Sphere’ – kicked off on September 29, and was scheduled to run until December 16. However, according to new reports, it seems that the band are set to be adding more dates to the residency.The speculation arose after outlets like The New York Post claimed that U2 are set to add a total of 12 more dates to the list while organisers continue to seek out other acts to take on the headline spot at the $2.3billion venue.It is not yet clear whether these 12 extra dates have been locked in or not, however, with Bono and co.
