ABBA and the rise of the work-from-home rock star

Thursday night and the lights are low, as the four members of abba, one of the most successful musical acts in history, take to the stage for the first time in nearly 40 years. Or do they? To the crowd at a purpose-built arena in east London, abba’s quartet—Agnetha, Björn, Benny and Anni-Frid—look authentic, their sequinned dresses and feathered mullets swaying to the beat provided by a live band. Yet the singers are computer-generated illusions, captured as they looked in 1979, and their voices a blend of recordings from nearly half a century ago. The virtual “Abbatars”, who played their first concert on May 26th, will perform seven shows a week while the human band members stay at home and collect the royalties.
