After a 40-year hiatus legendary band ABBA is back. And they set off from their new album, Voyage, towards a series of revolutionary shows, taking place in London throughout this year, featuring holograms of the group members. The Swedish pop group had not released new songs since 1981. The announcement of their return was celebrated all over the world. Voyage, composed of ten songs, is the result of a project ABBA has been working on for years: a show with holograms, whose protagonists will control the movements of their avatars, which will represent them looking as they did in 1979.
