KingBrilliant, I think you have to do it for the song, and because you love to sing. That's exactly what the audience picks up on. That's where the energy starts. Realizing that the audience has joined you in that feeling (and the reason for the power I was initially talking about) is what happens later.

I sing mostly chorus songs, but I've seen people do it with ballads. I've seen them close their eyes and go off into the aether someplace. It's not like their closing themselves off from others - more like gathering concentration and focusing on the song. They pull people in rather than push them away. When the song is over, people slowly remember where they are, and remember to applaud.

Naemanson, that connection is the power I'm talking about - the connection and realizing it's there.
