BTW: I haven't listened to the Jansons/Oslo M9 in a while but my memory tells me that the timings are similar to the Barenboim one.
I noticed that the timings are quite similar to the mythical Barbirolli’s Ninth.
Barenboim 77'58'' (26'30" / 15'12" / 13'09" / 23'05")
Barbirolli 78'32'' (26'53" / 14'53" / 13'38" / 22'57")
It is remarkable as Barenboim was initiated in Mahler by Barbirolli. DB tells as he usually played Mozart piano concertos in the first part of Barbirolli´s mahlerian concerts in Manchester. Now DB owns Barbirollí’s Seventh marked score.
My rate for the Barenboim Ninth is just 6.5/9
The central movements are extraordinary, but first extravagant and fourth dull. The sound is good to me, and the playing extraordinary... but the real thing, the Staatskapelle I listened to in the Berliner Mahlerfestage, was poorer.
Cheers
