Performing next...

So i am wondering if there is anything you can do to make people think you are a good musician without even hearing you yet. Lets say that you are at a guitar competition. Each contestant gets to do a 3 minute solo, with 5 minutes in between to set up. Would there be a way to set yourself up for success during that five minutes? Is there a way to use the idea of musical context to make yourself more exciting, enjoyable, and ultimately, a winner? Could you create a context for the music you are about to play that would get the judges attention, and make them hear your music in a different, hopefully better way? I guess some ideas would be to talk. What would you say? How do you want to come off to the judges? Would it be wise to be cocky, and then live up to that cockiness once you start playing? How about coming off as a wise, knowledgable musician? Maybe even coming off as shy or unassuming, and then tear the roof off of the place from the second you start. You could probably influence how the judges see you and your music by how you dress. They will be watching you set up, so making sure that your set up is as impressive as your solo couldn't hurt. Maybe the way that you set up, like putting something in a place where it wouldn't normally be to make the judge say to themself, "I wonder how they are going to use that?" A lot of times, a catagory for judging is originality. Could you get the judges thinking about originality before you even start by doing something odd? You could include something in your list of influences that could spark someones interest. I guess that ultimately, the goal is to, other than win, get the judges to be interested in hearing what you have to play, get them to be turned on rather than off, and to create a platform for your music where it is better recieved than it would have been if you haden't taken all this into consideration.
