Don't get scared-I don't read the National Review. This was, however, passed on by a friend and have felt the same way for years about the burgeoning amplification of everything from music to Broadway. Good read:
I find most movie theaters too loud for my taste (and ears). The other issue musicians deal with is the idea that every note should be perfect in a live performance. I agree, it should be, and do my best to make it so, but there's only one "take" and we're human. That said, professional groups rarely make an obvious (to the average, or even trained, listener) mistake. The level of musical ability in the top groups (any genre) is amazing, IMO.
I agree that there is way too much amplification. The trailers in movie theaters can be horrible I agree. When I went to see Skyfall, the bass during the trailers was so loud, the walls and floors of the theater where vibrating so badly that I thought the theater would collapse. That was not the case during the film so it was clearly deliberate. I have yet to hear issues with loudness at jazz clubs like the Blue Note or Birdland in NYC and I hope I never have to. As for classical music, nothing beats the sound of an unamplified orchestra. I will be back at St. Martin's In The Field in August and can't wait for that experience again.
