We'll look at some 20th- and 21st-century American music this week. Can it tell us where music is headed in our century? No, you need a crystal ball for that.
Similarly, at the cusp of the 19th century, no one could have predicted where music was going. But something was about to happen, and Beethoven's second piano concerto was a harbinger of what was to come.
Musical evolution then and now: we know what happened then, maybe we'll catch some hints at what's about to happen now.
