I've watched the Metropolitan Opera on Great Performances and attended many operas in Staatsoper and Volksoper in Vienna, Austria and in Salzburg, plus a Monteverdi opera at the State Opera in Budapest, Hungary, but this TV production I saw so long ago has always stayed with me. I love the Puccini music and Teresa Stratas has always been one of my favorite opera stars. I saw her in the lush production film of La Traviata in the theater, on TV again in Amahl and the Night Visitors, and in The Ghosts of Versailles broadcast on PBS. And every time she takes my breath away. Although retired now, she was the quintessence of aa beautiful star with a beautiful voice that so seldom goes together. ( The only other star I can think of in this category is Lily Pons, of whom I have only heard recordings and seen photos.) In La Ronnie, Stratas has a perfect role, that fits her like a glove and she is mesmerizing.
