4 Non Blondes were an early-1990s American alternative rock band. Lead vocalist Linda Perry has since released solo work and produced songs on hit albums by P!nk and Christina Aguilera.

4 Non Blondes had a huge hit single in 1993 with “What’s Up”. A year later, DJ Miko remixed the track as a dance song, and it became a hit again, on radio and in clubs.

In 1995, 4 Non Blondes contributed the song “Misty Mountain Hop” to the Encomium tribute album to Led Zeppelin. Linda Perry went solo in 1996 and the group disbanded after recording, but not releasing, their second album.
