When the Concertgebouw play at Carnegie, it is hard to imagine that any other orchestra could be as good or better. Then we hear Vienna and Dresden (we we shall this season), and we realize that the great Central European orchestras flourish in spheres all their own, and that it is a fool’s errand to attempt to rank them. Still, when it comes to communicating what a composer wrote, rather than a particular tradition of playing, the Concertgebouw remain unsurpassed. And if one refers back to the magnificent legacy of recorded performances under conductors associated with other orchestras—Walter, Klemperer, Szell, Monteux, and others—one consistently finds that their performances with the Concertgebouw represent their very best work. This year’s visit went right to the mark.
