I attended a concert by Alanis Morissette the other day in Tel Aviv. A critic of the local Israeli newspaper Haaretz found she did not sing well, but despite that everyone in the audience loved her performance.
This presentation design blog is not the right place to go into technical artist reviews. What is interesting however, is to see how Alanis managed to win the crowd over simple by being her natural self. No professional crowd pleasing techniques, no real eye contact into the audience, just pacing back and forth staring in the distance left and right of the stage. She actually came across as shy.
The audience wants you to succeed, and preferably using your own natural style.
