Joni Mitchell was running away. From what or where to have never been as vital in Mitchell’s songs as her in-betweens—between relationships and cities, between heartbreak and repair, between chords and tenses. From her early song “Urge for Going” through her travelogue classic Blue and beyond, Mitchell typified the woman wanderer, rarely represented in music. Hejira, her sprawling eighth album, embodies this quintessence.
