Among the greatest operas in Richard Strauss's oeuvre, "Der Rosenkavalier (The Cavalier of the Rose)" spins the tale of the Marschallin (Elizabeth Whitehouse), a dowager struggling with old age. Making the transition more difficult is Octavian (Ildiko Komlosi), a lover many years her junior. This 1997 Palermo production, under the baton of maestro Pier Luigi Pizzi, co-stars Daniel Lewis Williams as Baron Ochs, the Marschallin's obnoxious cousin.
