There was time when an all-female group didn't write its own songs or play its own instruments. Then came the Go-Go's. They did both, while also becoming one of the biggest bands of the early MTV era. Charlotte Caffey, Belinda Carlisle, Gina Schock, Kathy Valentine and Jane Wiedlin actually rose out of Los Angeles' late-'70s post-punk scene, but they had higher aims. "We Got the Beat," which Caffey is said to have written in basically five minutes, ensured the Go-Go's would never toil in local obscurity. Hits like "Our Lips Are Sealed," "Head Over Heels" and "Vacation" confirmed their nervy genius with pop hooks, good looks and fearless attitude. They'd become the first – and still only – all-female group to write and record a No. 1 album.
