A comic ballet based on two stories written by E.T. A. Hoffmann, Coppélia centers on a doctor who has made a life-size dancing doll so life-like that a young man becomes infatuated with it. World-renowned dancer Ramon Oller, a guy known for his work with some of the most celebrated international dance companies including Ballet Hispanico in New York and the Spanish National Dance Company of the National Ballet of Spain, choreographed the Cleveland Ballet world premiere that takes place tonight at 7 at the Ohio Theatre, where the performance repeats at 1 p.m. tomorrow. Tickets are $20 to $49. (Niesel)
