Watched these last night. I had no real knowledge or exposure to either symphony, except hearing snippets of 3 occasionally.
This was a strange night for me, i really really enjoyed 2 the flow of music was fasicinating and the second movement paticularly with all the volin play was superb.
The 3rd with the exception of the first and last few minutes i found very procedural and somewhat boring to be honest, it reminded of Bruckner quiet loud quiet loud etc, it was almost as if techniques were being shown off just for the sake of it with no musical story. Now maybe hearing the 2nd first put me in a certain frame of mind but the analogy that came to mind was that the second was like driving a Lotus, very direct and emotional with nothing flashy but still very soul stirring. The third was sort of a Lexus, very structured and nothing wrong with it but no soul or emotion.
These are first impressions and I would never of course claim any expertise, they are just raw initial reactions.
