The first Jefferson Airplane album was folk rock, with Signe Anderson as the female singer. She tried touring with her newborn, but soon realized she needed to be a full-time mom. (She still performed in small bands up until her death about 10 years ago).

The albums that followed with Grace Slick were very different.

I know it's stretching/breaking the rules, but same with Steve Miller. Sure he had other albums, but C'mon. It was really only one.
