Wikipedia on the Bangs:
When Susanna Hoffs joined sisters Vicki and Debbi Peterson to form a band in Los Angeles in December, 1980, the trio briefly christened itself The Colours, shortly renamed itself The Supersonic Bangs, but was soon shortened to The Bangs. The band was part of the Los Angeles Paisley Underground scene, which featured groups that played a mixture of 1960s-influenced folk-rock and jangle pop with a more modern punk–ish/garage band undertone. In 1981, the threesome recorded and released a single (Getting Out Of Hand b/w Call on Me) on DownKiddie Records (their own label). In 1982, the trio was signed to Faulty Products, a label formed by Miles Copeland.
The early Bangles line-up of Susanna Hoffs (vocals/guitars), Vicki Peterson (guitars/vocals), Debbi Peterson (vocals/drums) and Annette Zilinskas (vocals/bass) recorded an EP in 1982 and a single, The Real World, was released. A legal issue forced the band to change their name at the last minute so they dropped the "The" and added the letters "les" to the end to become Bangles.
