Girl groups are not a 90s invention. If you want to talk about "the" girl group, then that's the Supremes.

The Sounds Of The Supremes show an energetic, vocally and choreographically perfect
stage show. In the extremely fast-paced performance, the three ladies inspire with classics like "Stop In The Name Of Love", "Baby Love" or "Where Did Our Love Go".

Their voices, the sound, the outfit and the presentation as a unit have been the key to their success for years.
