I can't really hear the audience applause when I'm on stage. I'm totally immersed in the piece. But sometimes I get a lot of it and wonder, "Now, why did they applaud here?" If it's a white crowd, they usually applaud because they think it's a pretty movement. If it's a black crowd, it's usually because they identify with the message.
