Last Thursday I heard Haitink conduct M4 with the CSO. He used a slowish tempo in the first movement, and I thought that tenuto phrasing dulled the irreverent aspects of the music. Similarly, the scherzo didn't really come to life, though we know that Haitink does not tend to emphasize the demonic in Mahler. Within these limits, the orchestra charactized this music nicely.
To my ears, things improved in the last two movements. The slow movement was gorgeously done, and the finale was just as good, with Kara Ek in beautiful voice.
Frank Peter Zimmermann was to have played the Berg Violin Concerto, but cancelled due to illness. Haitink led the Schubert Fifth instead, in a soft-focus reading that favored a smoothly Romantic rather than a more sharply etched Classical view of the score.
I do not know if a CSO Resound issue of the Mahler is planned.
