Anime News Network: 1941: Once upon a time in New York City. There is a stage in a club called "Minton's Play House" in Harlem, open to all comers, and open every night. Night after night, they play jazz sessions, competing with each other, young jazz men with a new sense gathering, playing, and learning until at last they create a new genre unto itself. They are sick and tired of the conventional fixed-style jazz. They're eager to play jazz more freely as they wish.
