What is the difference between the New York City Metropolitan Opera and New York City Opera?
They are two distinct companies, both located in New York, and both based in Lincoln Center. The Metropolitan Opera Company performs at the Metropolitan Opera House. The New York City Opera performs at the New York State Theater. A few generalities: NYCO tends to hire more Americans, more younger singers, and do more unusual repertoire (including more American operas) than the Met. They have very different histories, and the rivalry between the two is long-running and has been well-documented.
