Just last week, my health care company put me on hold and switched on its automatic music long enough for me to hear “Parsifal” in its entirety, something I have never accomplished at an opera house. And opera is only a small part of my health company’s repertoire. Where else could one hear the entire oeuvre of the Captain and Tenille before being told that a representative would be available shortly and being switched to Chris Bottie and Diana Krall? It is like to listening to a college radio station or WBAI without the politics.
