In 1969, high priestess of funk Betty Davis recorded two legendary sessions produced by her then-husband Miles Davis at Columbia's 52nd Street Studios in Manhattan. The band consisted of Mitch Mitchell (Jimi Hendrix Experience drummer), John McLaughlin (guitar), Herbie Hancock (keys), Billy Cox (Band of Gypsys bassist), Wayne Shorter (sax), and Larry Young (organ). Teo Macero co-produced. In nearly 50 years, those jams have never been officially released or even bootlegged.
