Watching a production of Tannhäuser on YouTube. No English subs, and I have never seen the opera before. But I am reading the detailed plot summary on Wikipedia as I go. Armed with that knowledge, I can follow the music and stage action well enough. This production has very simple sets and is set in modern times. T is a painter instead of poet, and Venus was completely naked for the first 20 minutes. I think it's from Barcelona.
My goodness, this Shimkus family is talented! (Her older brother is an even more colossal pianist.) Fabulous playing and sound. (Well, parts of the Bach Toccata are a bit fast for my taste.)
I don't have that particular set, nor the K.428 w/Amadeus... However I do have some of their Mozart quartet recordings. What do they consider "The Great String Quartets"? The later ones? I have an individual album (below) with two of the last four quartets on it -- possibly duplicated in your set:
Usually the quartets dedicated to Haydn: 14, K.387; 15, K.421; 16, K.428; 17, K.458; 18, K.464; 19, K.465; the "Hoffmeister": 20, K.499; and the "Prussian Quartets": 21, K.575; 22, K.589; 23, K.590
Now playing the following CD with the harpsichord version of the foregoing works from my JS Bach collection. The performer was fellow Canadian Kenneth Gilbert ...
While I was still working I went nuts on the box sets but now that I'm retired they are few and far between.
I'm also retired and I bought a house about a year ago. I was really good about not buying music for about 8 months. I need to chill again with the purchases for a while. Hastings is closing, but I'm staying away.
Although I hear you, and sympathize, something tells me you have a CD (or 1,000) you can listen to in the meantime.
Now listening to "Grieg - Sonatas pour violon et piano" performed by Olivier Charlier and Brigitte Engerer on Harmonia Mundi.
If your definition of a duplicate is simply the same work but by a different performer, it is not a duplicate to me.
