and, while i can appreciate his work as a mathematician - as well as a classical guitarist - i do find that he gets prodding rather quickly, as the lack of emotional investment quickly reduces the artistic value of the work.
so, it is perhaps worth pointing out that so much of his work was commissioned - that is, purchased for a sum - rather than produced for purely artistic motives. it's rather obvious.
that said, the novelty saves it from the kind of artistic death one hears in a rossini or a mozart. bach may have been working for profit, but he was exploring a new system of tonality, and so there is this playful dimension to much of it. but, this is the appreciation of a mathematician, and not of an artist.
i would give him a fields medal before i gave him a grammy.
and, john williams was better at guitar than at film music, too.
