Watch the Performance Set online guitar lesson by Mimi Fox from Flying Solo
I recommend that you tape all your shows over a period of time and listen to the flow of one song to the next. You will quickly learn what works and what doesn't work. Common sense dictates that you don't start a show off with your most complicated and longest number. I like to start with something more accessible to get the audience with me. Once this happens, you can begin to get more complex songs across successfully.
