ABBA

ABBA took the gleam of Europop and the sugar rush of disco and built something sturdier than either, a Stockholm hit factory run by two couples. Agnetha Fältskog and Anni-Frid Lyngstad sang out front and Björn Ulvaeus and Benny Andersson wrote the songs, with guitar, piano, keyboards and even accordion behind them. They won the Eurovision Song Contest for Sweden in 1974 with "Waterloo", and from there they did what no act from outside the English-speaking world had managed before, landing hit after hit in Britain, America, Australia and beyond.

The shine had a shadow. Both marriages, Fältskog and Ulvaeus, Lyngstad and Andersson, came apart, and the late records turned darker and more inward because of it. The group split in December 1982; Andersson and Ulvaeus went off to write for the stage and screen while Fältskog and Lyngstad went solo.

It didn't end there. ABBA Gold, released ten years later, became a worldwide best-seller, and Mamma Mia! put the songs on stage in 1999 and on film in 2008. The Rock and Roll Hall of Fame inducted them in 2010, and in 2021 they came back with Voyage, their first new album in 40 years, followed in 2022 by a concert residency starring digital avatars in a purpose-built London arena. On the countdowns, "Dancing Queen" still rules the floor.
