I visited that museum, years ago, robomatic.
I remember the images (artistic, not photographs)
of adult Chinese women with the consequences of foot-binding.

Another angle of the influence of Wagner.
There is an essential genre of music,
essential to the twentieth century and the present century,
of sound-tracks for motion pictures.

Not Wagner alone, of course, but the whole legacy of opera in general
is brought to bear in composing feature-film sound-tracks.
Recall Erich von Korngold, sound-track composer for such films
as "Captain Blood,"
who got his start composing both light operetta and
full-on serious operas in Vienna.
Hollywood was quite the destination
for emigré European composers, especially Central Europeans,
in the twentieth century.

I reckon that film audiences, especially younger-generations of film sound-track composers,
have been soaking up that European influence --
which decidedly includes Wagner --
more than many of them appreciate.
