I've been listening to Michael Gielen's first recording of M9th with his orchestra, SWF-Sinfonieorchester Baden-Baden, that was released on Intercord label in 1991. I recall my lukewarm reaction when I first heard the recording but on this revisit it grows on me. If nothing else, the orchestra plays beautifully and it is recorded in extremely transparent, crystal clear sound that is not wanting warmth and ambiance. All the instruments are clearly audible no matter how softly they are played, while they never sound as clinical or cold as we might expect from this kind of sound. As for Gielen's first-at-go with the symphony, there are a few strange, quirky touches that I cannot quite buy, e.g., some juggling of tempo and weird balances in the brass in the opening movt., but overall he presents the piece with confidence and a good shape. The two inner movts. come off best in this reading. I wish he had take the finale a bit longer (clocking in 22 min. here) but that could be his way of interpreting the movt.
I also heard Gielen's second recording with the same orchestra available on Hanssler label. Although the new version has a few improvements such as audible tam tam and better tempo relationships, I cannot say I prefer it to the earlier recording; for one thing, the orchestra was not in top form on the day of the live concert (listen to the shaky trumpet in the second climax of I.). The sound, without much depth and clarity, wasn't all that great either.
All in all, Gielen's first M9th is worth seeking for the sheer brilliance of the orchestra and the sound quality.
Next is Gielen's M7th....
