FWIW I don't set great store by the words of NL (No offence intended, Pim Derks).
In NL's words,
What it cannot do is heal the schism that Korngold left behind – a seismic faultline in the musical process that has prevented the best classical composers from engaging seriously with the cinema, the most popular art form of our time.
Who does he mean by "the
best classical composers"? Mark Anthony Turnedge? Harrison Birtwistle? I'm sure that the willingness of Joe Public to listen to music by John Williams and Danny Elfman says more about the accessibility of their music than the opinion of a critic who seems to suffer from tunnel vision. Is he dismissing composers like Vaughan-Williams, Britten, or Walton? all of whom wrote music for movies.
As I see it, Korngold, as one of the first composers to write music for the new recording technology, had the unenviable task of blazing a trail, developing new skills and laying foundations for the artists who would follow.
As for the
seismic faultline in the musical process
, wouldn't a "Mind the gap" sign take care of that?
