4 Non Blondes was an American rock band from San Francisco, California, formed in 1989. The group was formed by bassist Christa Hillhouse, guitarist Shaunna Hall, drummer Wanda Day, and vocalist and guitarist Linda Perry. Prior to the release of their first album, Roger Rocha replaced Hall on guitar, and Dawn Richardson replaced Day on drums. They hit the charts in 1993 with "What's Up?", their only major hit single. Perry left the band in 1994 to begin a solo career, and the remaining members disbanded shortly after.

Bassist Christa Hillhouse and guitarist Shaunna Hall had been roommates and met drummer Wanda Day when they joined a band she was playing in. When the three left that band they started playing as a three piece but after seeing Perry sing at a solo performance Hillhouse and Hall asked her to join as vocalist. According to Perry, she and Hall were at Nightbreak, a San Francisco club, and when it was mentioned the trio was looking for a vocalist, Perry announced she was a singer to which Hall replied "I know". Their first rehearsal was supposed to be at 6 PM on October 17, 1989, but shortly after 5 PM the Loma Prieta earthquake hit the San Francisco area.[

The band was signed to Interscope in July 1991 following a performance at the Gavin Convention where the band opened for Primus on Valentine's Day of the same year. As they began pre-production for their debut album, Day was fired from 4 Non Blondes and was replaced by Richardson. In 1992 while recording Bigger Better Faster, More! the album's producer, David Tickle, felt that Hall's guitar playing was "not happening" so she was let go from the band as well. Guitarist Louis Metoyer finished the record. Roger Rocha joined after completion of the album and would stay with the band until 1994. After 4 Non Blondes, Day went on to join Malibu Barbi. Day died on July 10, 1997.

4 Non Blondes contributed the song "Mary's House" to the film Wayne's World 2 in 1993. They also covered Van Halen's "I'm the One" on the soundtrack for the film Airheads. They later contributed "Bless the Beasts and Children" to a 1994 The Carpenters tribute album If I Were a Carpenter, and "Misty Mountain Hop" to the 1995 Encomium tribute album to Led Zeppelin.
