For decades, Joni Mitchell’s life and music have enraptured listeners. Through extensive interviews with Mitchell's peers and deep archival research, Powers takes readers to rural Canada, mapping the singer’s childhood battle with polio. She charts the course of Mitchell’s musical evolution, ranging from early folk to jazz fusion to experimentation with pop synthetics. She follows the winding road of Mitchell’s collaborations with other greats, and the loves that emerged along the way, all the way through to the remarkable return of Mitchell to music-making after the 2015 aneurysm that nearly took her life. Along this journey, Powers’ wide-ranging musings on the artist’s life and career reconsider the biographer’s role and the way it twines against the reality of a fan.
