Reminds me of a Cat Stevens concert I was at several years ago. Not being a C S fan, it was one of those things I was talked into... like,"hey, I've got some extra tickets, etc". Can't remember what he sang, only how good he was because of the passion and energy he poured into every ounce of his singing. That's contagious! As a listener, you become caught up in the performers enthusiasm, even if it's not your favorite music!
I never forgot that experience. It taught me that if you want to perform sucessfully, you must have a passion for your music... and it must project to the audience. On the other hand, here are some things you can do if you want to go in the opposite direction:
1. Have your nose burried in your lyrics
2. Have lengthy discussions between songs re what's next
3. Fiddle with your drum machine before starting a song
4. Not using Registrations and taking too long between songs
5. Not playing what's necessary to keep dancers on the floor
6. Getting up during a song for a drink!
7. Wearing headphones to listen to the game!
8. Always looking at your watch and yawning!
Actually, I've never seen 6,7, or 8, thankfully, but I've seen much of 1 thru 5. I'm sure I missed some.
