Interesting, how many real gigs have You made? You don't like to watch at people who possibly are not interested in your music playing at gig. The thing could be, that Your band is not progressing needed as much. In reality every gig You play must give You more advantage for the next one, playing (not technicaly) to keep those listeners more interested in Your music. If You like to play, just change something in Your music as You would think someone would like better at next gig. It's not a standart problem, it is "time" and experience.
