kind of stumbled their way into , their first album in 40 years. In 2016, the group began working on ABBAtars, a virtual concert based on the band's blockbuster 1979 tour and featuring 3D renditions of , , and . and decided they should write a couple of new songs for ABBAtars, thinking that if it was going to replicate the experience of an tour, the group would surely be peddling new material. The two new songs soon turned into three, then into the ten songs that comprise . Throughout the process, operated under the notion that if a song didn't live up to their standards, they were under no pressure to release it; they already had two songs they liked in the can for ABBAtars. were happy to participate so long as they didn't have to promote the resulting album, a compromise happily accepted. And that's how wound up with , an album that uncannily sounds and feels like a classic album, one that could've been delivered not long after wisely decided to not follow any stylistic trend or adopt any modern production technique; while there may be some digital gloss here, voices aren't auto-tuned and rhythms aren't sequenced. is recognizably music, a quality that's simultaneously thrilling, disorienting, and a bit corny. managed to revive the big, dramatic melodies that defined a good portion of their catalog -- the way the opening ballad "I Still Have Faith in You" soars can cause goosebumps of recognition -- and they do convincing nods at their lighter, danceable moments on the singles "Don't Shut Me Down" and "Just a Notion," yet they also offer reminders of their Eurovision origins with the overheated showstopper "I Can Be That Woman" and vaguely ominous, vaguely disco "Keep an Eye on Dan."
