The Bach Cantata here is marvelously moving, so let me put in my $0.02. When Bach wrote his music, he was also at the cutting edge of the technology of his age. The pipe organs were great accomplishments of that mechanical age. The churches then embraced the technology and music as new wave churches of our age (and with similar resistance).

Bach was an ultimate nerd, adept in technology of his generation. He knew about organ construction like few did and he earned an income as consultant from pipe organ construction projects that required much risk taking and investment. One has to be technical enough to know a lot about the physics of sound producing, metallurgy (look into the tin/copper content of the pipes to make sure the builder hasn't taken shortcuts etc. ), inspect bellows, air controllers, and suggest design changes, etc.

To the ordinary towns people this might have looked like Moog synthesizer or Hillsong innovations of today. Lets not forget that Bach faced significant career threatening opposition on the musical structure of these very Cantatas that were composed when he was Cantor at St. Thomas in Leipzig where he taught music. His music was too new for most of them too...
