Weaving together classic folk tropes and rousing personal yarns, this bohemian British singer set the bar high for her musical descendants. She released her first single when she was a teen in 1965, and went on to work with Simon & Garfunkel, Jimmy Page, Donovan, Levon Helm, Nick Drake and John Martyn (whom she married). But it's her ability to spin delicate blues and stark, unsettling roots music that really stands out. Weathered, storied vocals sit atop syncopated beats, hammering keys and finger-picked guitars as Martyn leads listeners on a journey of heartbreak, resurrection and love.
