4 Non Blondes

4 Non Blondes was a rock band from San Francisco active from 1989 to 1994. Best known for their hit single "What's Up?" the group released one album, Bigger Better Faster More, which spent over a year on the Billboard charts and sold 1.5 million copies. The original all-female lineup included Linda Perry, Christa Hillhouse, Shaunna Hall, and Wanda Day, though line-up changes occurred before their album’s release. The band split soon after Perry departed in 1994.
