Listening to Lenny do Der Rosenkavalier - about fifteen minutes shorter than the full-length version. This one is not as lush or refined vocally as the von Karajan. And Gwyneth Jones is a real scooper, I must say. Christa Ludwig is on both - here she's the lead, on the other one she's Octavian. Sound is very good, but it just isn't in the same ballpark as the von Karajan, which is amazing since the von Karajan was a 1956 stereo and this is 1971. Still, it's enjoyable and glad to have both - not sure I need any others, unless folks have a suggestion.
