Back in 2017, at the Jazzopen Stuttgart Festival, the great Quincy Jones put on a show that elicited many rapturous standing ovations from the capacity crowd. To kick things off, the seventy musicians of the Stuttgart Chamber Orchestra and the SWR Big Band step out onto the stage. It is a warm summer’s evening and they play a grand opening medley in the fading light that seamlessly blends classic jazz with Michael Jackson numbers like “Wanna Be Startin Somethin.”
