Nothing wrong with that, but for me I much prefer "historically informed" performances on modern instruments, e.g. what Charles Mackarris does. The old instruments certainly are different, and interesting in their own way, but I'm glad they evolved into their current form. But, especially for Haydn,I'm unrepentant old school. Give me Bernstein, Jochum or Beecham.
Of course there are exceptions. I'm a recovering clarinetist and the Mozart Clarinet Concerto always sounded like a hack on the modern instrument because it didn't play as low as the basset clarinet for which it was composed and certain runs had to jump up an octave in the middle. It sounds much better on a historically accurate instrument. But stuff like gut strings and A 430 aren't my favorite thing on the menu, although I will order them from time to time.
Oh yes, the recording with the Academy of Ancient Music used the orginal basset clarinet of course.
But I must admit I much prefer Mozart's Piano Concertos on a modern Grand over the fortepiano versions used on some recent recordings.
BIS has released some Mozart Fortepiano pc's as hi res downloads but I quickly tired of them and now listen to Mozart played on Steinways and other Grand pianos.
And I also prefer BIG orchestras over chamber orchestras in general even with classical works like Mozart symphonies.
I much rather listen to Bruno Walter, Böhm or even Karajan in the late Mozart symphonies than the Mackerras Linn Scottish Chamber Orchestra recordings which I find a bit thin and steely non vibrato style and a bit lacking in melodic beauty compared to the old greats.
Imho a good lesson in how to play/ perform and conduct, the heavenly beautiful second movement of his last symphony can be seen and heard in the conducting masterclasses recently given by Ivan Fisher and the Concertgebouw on YT.
And in spite of some current performing preferences I repeat again ,sorry to be a bit repetitive on this subject,according to letters to his father, Mozart really liked hearing his music played by big orchestras, big even by our modern standards in some confirmed cases, and had nothing against vibrato.
As CM quoted Mozart liked a "buttery" warm sound from the violin and a good way to achieve that is gut strings and a bit of vibrato.
"Historically informed" isn't always as informed as it claims to be.
Compromises for economic reasons and simply lack of more musicians ruled more than actual musical preferences I suspect.
Another not much known fact is that to make the period keyboard instruments sound a bit grander then they normally did, Mozart sometimes had special bigger wooden extension boards added to the fortepiano pedals.
He was apparently very interested in the bigger and more sonorous instruments appearing on the market in the 1780s and even used an "incognito" name when trying out new instruments at shops, sometimes using the name "Trazom" instead of Mozart, according to Robbins Landon in his book "Mozart the Golden Years" which I am currently reading.
