Mitchell is one of a handful of women in her era who were invited into the music world’s clubby little definition of genius, and Powers has the chops to explain exactly why that was so, both through her virtuosic writing on Mitchell’s musicianship and creativity and through a sophisticated interrogation of the gender and race politics of the era. She shows us how we can love an artist like Mitchell and let her be human, too, how we can understand her genius from — forgive me, Joni — both sides now.
