I'd need to do a count, but of my favourite of his symphonies 3,4,5,6 & 9 I would have 7-8 of each. I have 2 complete cycles - Michael Tilson Thomas with the SFO and Gregeiv with the LSO. I've listened to a couple from the Gregiev and they are just so uninteresting. I only bought it because of the good price and had just gotten an SACD player so was a little excited... I'm particularly interested in adding some Boulez recordings to my Mahler collection as I currently have none! This morning I reached for Bernstein's performance of the 2nd with the LSO. Yesterday I listened to a new disc that arrived, Barshai's recording of the 5th and I can hear what all the hype is about. Coming up I have 2 new recordings of the 3rd, Zander with the Philharmonia and Wit with the Polish symphony. Of the other Wit Mahler recordings I have, they have been rather uninspiring. But I thought his 5th was interesting enough to warrant purchasing some of his other Mahler recordings, a decision made somewhat made easier by the cheap cost of a Naxos disc. Actually, looking through my pile of unopened/unlistened to CDs I have a few Mahler discs. Mahler 2 by Markus Stenz with the Melbourne Symphony, 6 by Wit and the Polish National Radio Symphony, 5 by Barbiorolli and the New Philharmonia Orchestra, and 3 by Jonathan Nott and the Bamberger Symphoniker. I don't really have preferred performances in the typical sense, but I find small sections or passages in each that really speak to me. My Mahler affair started about 3 years ago and kind of never let up. I think I could be the complete opposite. I could listen to Mahler all day (and sometimes do) I bought it because a lot of those works I didn't have. It's the first box I've gotten, that so far, I have been listening to from 1st to last. The performances so far have been very good and the actual box is the best I've come across presentation wise.
