I wonder. The 20th century, particular the latter half of the 20th century, seems to have exploded the idea of each era being defined by a "movement," such as Baroque, Romantic, Impressionism. Even once-far-out ideas like atonalism, chance-music, minimalism and other "reject-what-has-come-before" movements seem dated. I personally think that many composers who in the past would have been "court" composers now work in TV and movies and that their music is shaped by the demands of those industries. Yet there are a million other composers doing a million other things in electronic arenas which we may not see. Is this the age of iconoclasts?
