i never understood the point of walking around and flailing about like i have a frog down my pants on stage. Even if you dont make a mistake, you look like an idiot. What matters is the sound resonating from your noise making instrument. be it a bass a set of drums a guitar or a microphone. You can even stand with your back to the audience and stay absolutly still. People will be impressed by the sound you're making rather than how quickly you can give yourself a headache while bopping your head up and down. If your art is music, share your music, if your art is showmanship go be a figure skater.
like it or not, musical performance has a large visual aspect.
get your head out of the ground and look around.
