I was on the fence because ordinarily I would almost certainly have attended this concert, but I opted for a trip to Milwaukee to hear "Symphonie fantastique" preceded by two Liszt works with Stewart Goodyear. Conductor was music director Ken-David Masur. A terrific concert and I'm glad I went.
On my two previous visits to the fabulous Bradley Symphony Center, I was toward the front on the main floor and found the sound warm but opaque. Yesterday I sat in the balcony and found the sound quite a bit better.
I've listened to the first movement of Rattle's new M6 with the BRSO, and while I think he has matured as a Mahler conductor, I still didn't find it quite convincing. Then too, I've heard fine M6s in Orchestra Hall with Haitink, Gielen, and Slatkin, and when I asked myself if I really needed to hear another M6 in congested and blaring acoustics, I answered in the negative.
Listening to the Jansons/BRSO M6, I found it a more involving performance than Rattle's, with a couple asterisks. The cowbells are clattery instead of atmospheric, the bells are inappropriately high pitched, and the hammer makes more of a sharp crack than the dull (but powerful) thud that Mahler specifies. Those aside, it's a strong performance that projects a narrative sweep from start to finish, with a sense of orchestral unanimity that few other conductors can match.
Meanwhile, on Idagio I listened to the Paavo Järvi/NHK M6 and liked it very much. Other than the cowbells being bashful, it checks all my boxes and is in the elite category of my favorites.
