Chas has a good point about applause and audiences. It brings to mind a gig I did last Wednesday, although different circumstances. The point is audiences may very well enjoy your music, but don't necessarily show it.

I was playing a variety of genre's for about two hundred patrons, and getting a smattering of applause, but there they were eating and talking. After my show, the MC got up and asked how the food was,small applaus. He then thanked me for playing, and the whole room stood up and applauded. Needless to say, I am playing there every week now.

People may not immediately react, but that doesn't mean they don't enjoy what you are presenting.
