Alvin Ailey marked the company’s 20th anniversary season by choreographing this solo for Judith Jamison. In Passage, Ms. Jamison portrayed Marie Laveau, the most powerful voodoo queen in the history of this country. Laveau lived in New Orleans during the 19th century and practiced snake worship, mystical spells, and other magic. To add, she was a master manipulator on the social and political fabrics of the time.
