These '90s Girl Groups Absolutely Dominated the Pop and R&B Scenes

En Vogue is still famously known for their impeccable vocals as a group. Their 1990 debut single "Hold On" opens with a minute-long, perfectly blended harmony (yes, that was a popular thing in music back then). While the group underwent several member changes in its lineup, En Vogue still managed to rack up six top 10 Billboard Hot 100 hits. In 2018, the group proved they were still hit-makers with the release of their first new album in 14 years, "Electric Café."
