Just one or two quick points here I think (for the moment)...
We like the way he perches on the very edge of his chair, and his evident pride in the size of his biceps, and (as does Mr. Iron) his Bach fugue - which is well-phrased but slightly too speedy. We also like his
Lutoslavsky. On the other hand he should be warned that the "jazz" will in the long run be very detrimental to his career; look what happened to poor Yehudi for example after he got involved with that Grappelli creature after 1973! The population of Japan is about one hundred and thirty million souls of course.
I did not think the fugue too quick - 3/2 is supposed to be basically a 'quick' tempo (otherwise the same music could be notated in the normal 3/4). One of the unfortunate legacies of the later-19th and early-20th centuries was completely to misunderstand the meaning of earlier Proportional Notation, and to make the opposite (incorrect!) assumption that the notation in minims and crotchets (as opposed to crotchets and quavers) "must somehow" mean that the tempo is
slower. Fortunately we have mostly moved forward from this basic misconception, and can now hear much of this music in the way its composer probably intended.
Yehudi's reputation did not suffer because of the Jazz - it suffered because when playing with Grappelli it became clear that he was being completely outclassed both musically and technically. Mr Grew is correct, of course, in seeing his mistake in trying to be the equal of his duettist, but it was not the Jazz in itself that injured him.
As for Mr. Berben's familiar fumblings and stumblings, it is all much as we expected - simply a case of over-confident sight-reading is not it? These failures of the executant are all the more argument for computerised performances as the way of the future.
Computerised performances will never - and should never - replace live performances. Where failings in an executant are evident, it is these that need attention and improvement. Sweeping them under the carpet and retreating into a world of only virtual reality does not address them.
