Miles Davis reached both a personal and critical nadir in the fall of 1972. Returning to New York following a brief but thrilling tour with a revamped nine-piece ensemble, he totaled his Lamborghini Muira and broke both legs in a gruesome, cocaine-strewn accident on the West Side Highway. The same week, his On the Corner LP was released to near revulsion from the music press. Yet, in the throes of his most fertile creative period since the spring of 1970, Miles refused to end the year a broken man – his studio sessions continued unabated from November into the following spring, often with the bandleader hobbled on crutches.

Miles would also make several changes to his live ensemble across the first half of 1973, including swapping out saxophonists, adding guitarists, ditching the tabla and sitar, and burning through keyboardists before taking over organ duties himself.
