Horn player, bandleader, innovator. The man with a sound so beautiful it could break your heart. Again and again, he broke with convention, and his bold disregard for tradition, his clarity of vision, his relentless drive, and constant thirst for new experiences made him an inspiring collaborator to fellow musicians and a cultural icon to generations of listeners. It made him an innovator —from bebop to “cool jazz,” modern quintets, orchestral music, jazz fusion, rock ‘n’ roll, and even hip-hop. The film features unseen footage, studio outtakes, and rare photos.
