Sunday marked the opening of L.A. Opera’s Der Rosenkavalier, which, following Saturday’s opening of Falstaff, completed a marathon weekend of well over 7 hours of opera. This new production is the latest in L.A. Opera’s Hollywood-influenced approach, this time featuring direction by screen legend Maximilian Schell. And in this case the influence is especially obvious as Schell sets the stage with actual projections from the 1925 film version of Der Rosenkavalier, directed by Robert Wiene of The Cabinet of Dr. Caligari fame. Though that might imply a hint of German expressionism, this production is pretty much all over the map stylistically, but is nonetheless fascinating in its design and musical talent. More on that next hour.
