Well, hard on the heels of Noseda/BBC Phil. doing the Cooke III version of M10, we get a new DG one with Daniel Harding/Vienna Phil. I have a pirate of that, and it's really good. Harding is sort of a Rattle clone, so comparisons with Rattle's Berlin remake could be really interesting (or really boring, depending on your point of view). In general, I think that Harding will be slightly faster than Noseda. I think that the Chandos one (Noseda) will have the better sound quality. If you've never heard Noseda/BBC Phil's recording of Prokofiev's "The Stone Flower", it's a knockout!
Another item of interest is an M4 with Sinopoli/Staatskapelle Dresden on Profil. Juliane Banse is the soprano. Mouret mistakingly lists this as being M9, which has already been released. But if look at hard the cover, you can see that it's the 4th (in G Major) with Ms. Banse. If it's not tooooo slow, this could be really interesting. For me, the SKD has just about the ideal orchestral sound for the 4th (along with the Czech Phil. and Concertgebow). And even it does turn out to be a slow performance, it still might be interesting. We'll see.
Of course, already discussed are the upcoming Rattle/BPO M9, and the Gergiev/LSO M6. If Gergiev just let go and went nuts on M6, that could be fun. We'll have to wait and see. I thought that Jansons definitely did his studied M6 better with the Concertgebouw.
There's also an M4 listed with David Zinman/Tonhalle Zurich (RCA). I'm not at all familiar with the soprano, Luba Organosova. Can anybody comment on her?
Last but not least, Decca is releasing the first and third Schumann/Mahler symphonies by way issuing a box set with all four symphonies. I'm happy for that, but it sort of puts those who already have the 2nd & 4th symphonies out on a limb.
