Celebration is an avant-garde fable played on bare platforms, masks serving as the primary costumes, and a score played by a nine-piece band instead of a full-sized theater orchestra. There are four main roles (a narrator, a young woman (Angel), a young man (Orphan), and a wealthy old man (Rich)) and a chorus, the Revelers, who play various roles. "At the musical's core is the struggle between youth and old age, innocence and corruption, love and ambition, and poverty and wealth, as Angel decides if she would be better served by her feelings for Orphan or Rich's willingness to fulfill her every dream.
