I apologize if she's already been brought up, but I would add:
Alison Mosshart(The Kills, The Dead Weather): Although I don't like the direction her bands have gone in after 2014 or so, The Kills' first four albums, and The Dead Weather's first two are among my absolute favourites. I could never figure out how The Dead Weather didn't become the biggest band in the world after releasing Horehound and Sea of Cowards.
