There are quite a few mentioned who I would not consider rock singers (more like pop, alternative, or jazz) but at a minimum, I think Pat Benatar, Grace Slick (maybe the greatest female rock singer ever), and Janis Joplin have to be added to the bojack’s original list.
Women Who Rock
There is an excellent new docuseries on Amazon Prime called "Women Who Rock".
This series goes pretty much back to the beginning and continues through today.
Highly recommended!!!
