SATCHMO AT THE WALDORF is a one-man, three-character play in which the same actor portrays Louis Armstrong, the greatest of all jazz trumpeters; Joe Glaser, his white manager; and Miles Davis, who admired Armstrong’s playing but disliked his onstage manner. It takes place in 1971 in a dressing room backstage at the Empire Room of New York’s Waldorf-Astoria Hotel, where Armstrong performed in public for the last time. just four months before his death.
