I've listened to this a handful of times through headphones from my laptop. My stereo is in a box at the moment. I agree the bass may be a bit weak, especially when compared to the NY Phil 7, but few orchestra's have anyone who can blow like Harwood can. Anyway, I found this to be a very coherent interpretation. It's not as agressive, as others, nor as rounded as Kubelik. The strings are very taut, athletic, the brass is a bit bright, and the woodwinds speak with such clarity in the scherzo and nachtmusik's that I was constantly impressed with their sectional playing.
I feel like Zinman's giving us a more 'sunny' side to this work. I also find this to be very well thought out and executed. Everything fits; tone, style, color and clarity. I liked the tempo, they seemed to be about right for me. He handles the gear changes through out this work with a very deft hand. They aren't the hard charging shifts your get from Kondrashin. A bit more mellow; laid back if you will. Over all I think this is a different take from the other 7's I've heard. Personally I really enjoyed it. Maybe I should have prefaced this by stating that I also enjoyed their 5th too.
