Why?
The Vänskä/Lahti performances in general to me have seemed both idiomatic and correct as well as superbly recorded. I have seen them perform Sibelius live as well and have been greatly impressed. Obviously I need to relisten to the Violin Concerto disc, but any indications as to what to listen for will be appreciated.
Very slow tempi, all seem to be one long adagio, no variations, or almost. Mannerisms like deliberate over studied playing, intellectual statements without essence, the violin recorded without a microphone but integrated into the orchestral sound, therefore barely noticeable when the orchestra plays loud, or when K, plays as soft as he can, not that it is necessary, but just for the show off. Empty headed music making from a musician with a big ego. Sorry for this tirade but you asked for it, and I feel pretty strongly about this disaster of a recording.
And dare no one say anymore that I think all discs I buy are wonderful, I would personally steer the bulldozer to smash all existing copies.
There!
