When we play (music) when we play

Playing live music or otherwise performing in a larp is a strange thing. You are using your real-life skills to do something inside a larp, and setting yourself up to potential criticism. You would like this to add to the experience of others while also enjoying it yourself, but there is the tingling feeling that isn't this making this all about you? Also, of course, questions of stage fright, how music you and other players know fits into the setting, questions of audience participation, entertaining the (already entertained?) players vs entertaining the characters and a bunch of other anxieties play into this area. And all of this, while being (at least somewhat) in character? How do people who play live music at larp deal with this?
