Abba

ABBA gained immense international popularity employing catchy song hooks, simple lyrics, and a Wall of Sound achieved by overdubbing the female singers' voices in multiple harmonies. As their popularity grew, they were sought after to tour Europe, Australia, and North America, drawing crowds of near-hysterical fans, notably in Australia. Touring became a contentious issue, being particularly unpopular with Agnetha, but they continued to release studio albums to great commercial success. At the height of their popularity, however, both marriages of the band members (Benny with Frida, and Björn with Agnetha) failed, and the relationship changes were reflected in their music, as they produced more thoughtful lyrics with different compositions.
