Carnegie Hall is, of course, one of the world’s great concert halls, just so long as you’re talking about symphonic music. But throw the best jazz band in the world on the Carnegie main stage, and you’ve got a major acoustical problem on your hands. The problem has to do with electronics – halls built to showcase the raw sound of an orchestra just aren’t built to deal with the high-octane amplification systems used by jazz and pop musicians. The problem can be overcome without too much trouble if the guy running the sound board knows how to do it, but a large percentage of board operators just aren’t used to working in such an environment.
