People look at the screen, at the ABBA Voyage event at Grona Lund, in Stockholm, Sweden, Thursday, Sept. 2, 2021. ABBA is releasing its first new music in four decades, along with a concert performance that will see the “Dancing Queen” quartet going entirely digital. The forthcoming album “Voyage,” to be released Nov. 5, is a follow-up to 1981′s “The Visitors,” which until now had been the swan song of the Swedish supergroup. And a virtual version of the band will begin a series of concerts in London May 27. (Fredrik Persson/TT News Agency via AP)
