Yes I like the Dresden 9 and look forward to the 4, though I disliked J Banse on Boulez's M4.
I picked up the Sinopoli Bruckner 4 in Australia while on holiday and like it a lot, very urgent, almost aggresive at times, but distinctive. Like Celi on EMI, out of the ordinary. As for the Sinopoli B8 (now deleted) that is stupendous. I recall the B9 was slightly dry sonically as recorded live in the Semperoper rather than the fabulous Lukasirche - I culled it for that reason I think but should probably rebuy...
I can understand why many will feel uncomfortable with Banse: she completely defies the traditional model of an "innocent" light soprano almost automatically expected in M4, for instance. But I find her musical intelligence and ability to so effortlessly shift color (and hence meaning) within even a single syllable an utterly irresistible proposition in a lot of the music she has recorded (good example: her Berg lieder with Abbado, or her Schumann for Hyperion). She is vocally very full and mature and interpretatively a bit too knowing or "artsy" to elicit enchanted reactions in most.
If I now confess that the unsurpassable ideal for me in M4 is Schwarzkopf (with Klemperer), that will tell you I don't really mind such qualities at all.
Someone I'd love to hear doing it: Christine Schaefer.
Glad to see I'm not the only one making fatal mistakes. It hast taken me several years and multiples of the original amounts invested to re-create my complete Sinopoli Bruckner collection. (Note of irritation: The B8 that I got from arkivmusic.com has such lousy graphics works in the booklet & inserts that I could myself do better with the cheap xerox machine I have. How can it be so difficult to do even a respectable job in copying, if quality copies is what you want to become known for! This is like done with your mom's inkjet with the ink running low, and on cheap bulk paper to boot. What a world of difference from the Japanese reproductions that save no effort to go far as even replicating the exact coating material and finish of the original LP sleeves, and all that for a price better than the Arkiv offerings. Now explain that, please.) Sinopoli's B5 and B9 were both recorded at Semperoper, but I can't recall now that having in any way been an issue. On the contrary, his B5 has reference quality to my ears (too long since I heard the B9 to say anything about it right now.)
Another victim of my many years in congested NYC apartments was the Sinopoli M4 with Philharmonia, which I in other words no longer own. Something more still to regret!
But enough ranting already.
