The Jazzmen looks main­ly at these three mae­stros’ lives off the band­stand, and how they wrote the sound­track for the civ­il rights rev­o­lu­tion. It also explores the Black-Jew­ish alliance of old— one where each of these African-Amer­i­can band­lead­ers had a Jew­ish man­ag­er and band­mates —and how that might offer a mod­el for today.
