As a performer, I’d like to thank you for dancing.
It’s true that this happens, though I personally think it is my fault most of the time. Over the years I’ve learnt to feel the audience, try and get their attention and slowly build up their mood. It’s true that some audiences are hard to please. I remember trying to play in Berlin and my girlfriend at the time said “look, think about it. The people that came here are the ones that couldn’t get a ticket for Tina Turner”. There’s Tina Turner, Robbie Williams, Joan Jett, Simple Minds and maybe even U2 all playing on the same day in the same city, and I expect people to be excited about coming to watch me in a little bar in some back alley? This I believe may be true of all big cities.
So it is true that in smaller town, where the audiences are not as “spoilt”, people will appreciate even a half-decent act a lot more. And they’ll be listening to the music, so if you’re good, you got a chance.
Thirdly, I have noticed that older people tend to respond to my own music better (and I assume that’s what you’ve been listening to). I don’t know why that is. Perhaps it’s our “free download mp3” culture. Perhaps younger people simply don’t remember what it is to go to a live concert, whether it’s Woodstock or just your local heavy metal band in the 70s. And they probably don’t care. But you do.
What I do personally as a way around that, is try and find ONE person in the whole audience that seems responsive. You can see it in their eyes. I pretend there’s nobody else in the room, and sing for them. I do not necessarily look at them the whole time (it could be a girl for example, and she might get embarrassed), but I notice their reaction, and try to play as if I’m auditioning for that one person. And usually everybody else follows. Which of course is a problem when there’s not many other people around to follow.
Oh and a final tip if you ever go on stage: never use a stool. Not even if you’re going to sing a ballad. Staning up forces you to move, and that helps the audience tune in better. I saw a huge difference in people’s reaction the moment I got rid of my stool. And of course it made me sing more dance songs and dance around on stage. (and also helped me lose weight, which is just a perk)
