4 Non Blondes was an American alternative rock band from San Francisco, active primarily in the early 1990s. The group is best known for their 1993 hit single "What's Up?", which became a global anthem. Fronted by Linda Perry, the band blended rock, funk, and folk influences. Despite their success, they released only one studio album, Bigger, Better, Faster, More! (1992), before disbanding in 1994. After the breakup, Perry went on to have a successful career as a songwriter and producer for artists like Pink, Christina Aguilera, and Gwen Stefani.
