Caldwell mounted many U.S. premieres and brought rare editions of standard works to her audiences. At the height of her career, she raised her baton over four of the top five orchestras, including the New York Philharmonic and the Boston Symphony Orchestra, and conducted orchestras in such cities as Pittsburgh, St. Louis, San Antonio, Atlanta, Mexico City, and Puerto Rico. She conducted ensembles in Canada, Sweden, South Africa, and Russia; was a musical director for Wolf Trap; and was the first woman to conduct at the Metropolitan Opera. She founded the renowned Opera Company of Boston, as well as the outreach effort Opera New England and a nation-wide touring enterprise, the American National Opera Company. Caldwell's undeniable zeal was evident in whatever she undertook, and her accomplishments invite reflection, showing what an opera company could and should be in America.Daniel Kessler presents Ms. Caldwell's life in flashbacks and explores her 1978 landmark production of Gaetano Donizetti's , which serves as a prime example of how she engaged with her creative Muse.
