I must amend my above review. Eight months on from the review, I am, while not less enthusiastic about the set, of a different mind concerning different recordings of Der Rosenkavalier. I have acquired a few more recordings of the opera, and only one of them so far has bumped this one off the top of my list. It is the 1958 studio recording for DG under the same conducter, Karl Bohm, recently re-issued by DG. While I still feel Ludwig's Marshallin to be the best, I feel that Tatiana Troyanos' Octavian has gone down my list somewhat. She is below Christa Ludwig's Octavian, which is second only to Irmgard Seefried's, who is Bohm's Octavian in '58. Schech for Bohm in '58, however, is, while more than adequate, no competition for Schwarkof, Ludwig, or Reining (Kleiber, '54). Rita Streich for Bohm's first recording is the equal of Edith Mathis on his second. With Ochs is where we come to the real difference. Kurt Bohme, on Bohm's first recording, is far superior to Theo Adam, who, like Schech's Marshalliln, is excellent, can't compete with the outstanding Edelmann, Bohme, and Weber (Kleiber). The sound quality is of marginal difference, for while one was made 11 years prior to the other, the first was in the studio, and the second was live. Also, I find that, contrary to what I would have though without hearing the recordings, the Dresden Staatskapelle outplay the Vienna Philharmonic. Since both of the sets are at mid-price, you must choose between an excellent Marshallin, outstanding Octavian, outstanding Sophie, and outstanding Ochs (1958), or an outstanding Marshallin, excellent Octavian, outstanding Sophic, and excellent Ochs, but with the added frission of a live performance (1969). Really, it's up to you to decide. Also, of course, there is Karajan's 1956 EMI performance, with Schwarzkopf, Ludwig, Stitch-Randall, and Edelmann, but if you choose that, I reccoment the mono version, because of slightly hazy sound and more recessed voices on the stereo version. Myself, I wouldn't want to be without all three, nor without Kleiber's and Knappertsbusch's excellent versions (on Decca and RCA, respectively).
