A. C. Douglas is concerned that Osvaldo Golijov represents "the future" of concert music. Mr. Douglas need not worry--the multi-cultural polystylism of Golijov, whose Ayre has received reviews both rapturous and reserved--is not the future. It is a future, one of a thousand stylistic flowers that will bloom.
Golijov is indeed having a big and very visible year. But so are John Adams, Tobias Picker, Jennifer Higdon, and Elliott Carter.
Some will argue that this year's celebration of Carter is a final blooming of a Modernism that is over, but I believe (and I don't think it is merely wishful thinking on my part) the next several years will see the growth and acceptance of what I'll call, for now, "neo-modernism".
In addition to the above named, Kaija Saariaho should be getting quite a bit of attention when her second opera, Adriana Mater, premeires in Paris.
In addition to the diverse styles of the composers listed above, we have neo-romanticism, totalism, jazz-inflected improvisatory music, and live-electronic music. Minimalism and serialism also have their adherents. I'm sure, at least I hope, that Mr. Douglas can find something in all of this abundance to like and admire.
