In defense of my own ancestors from "easetern eurpope etc" I must insist that the art of performing ballad-like songs is known and appreciated there as well. But concerts are not only about singing or virtuoso soloists; a good accompaniment or sophisticated arrangement also deserves an ear.

We all agree that various codes of etiquette apply for various styles. The problem is not only about rude audiences, inexperienced concert-goers (whose habits were formed while sitting in front of their TV sets), or conceited performers, but also about "misunderestimating" the character of an event. Good PR management will try to minimise these risks.
