I'd like to know what Roger plans to use for amplification. I'd sure like to hear that set up!
Something similar was done in Munich about 15 years ago by Philips in an attempt to prove to Sergiu Celibidache (conducter of the Munich Symphony and not a fan of recorded music) how good recorded sound could be so that he would agree to record with them. They sent out their head engineer and a couple of 18 wheeler loads of gear and set it up in the Symphonic Hall, including a giant electrostatic array capable of duplicating the sound energy of a whole live orchestra. The maestro dutifully sat and listened and noticed, in the piece of music being used to demonstrate, that after the repeat in the music the performance was identical to what had come before the repeat, i.e., they had spliced the same thing in because something had obviously gone wrong in the second part and it was easier than getting the orchestra to play it again.
Demo over!
Once again, Sergiu declined and Philips went home to Holland. It wasn't until after his death 8 years ago that much of his work was released by his family.
