Speaking as someone else who lives in Tacoma (253!), all you really can do is have fun with it.
No one else in this area is aware of the real capabilities of the hardware you are using.
No one is aware of this as an acceptable platform for music.
No one knows how they feel about it, and use that to your advantage.
Not to sound completely negative but, a mediocre performance is only performed with a mediocre attitude. It can be very intimidating to present something new to an audience that is not familiar with it, and I've been dealing with it for the past five years. Though each time I decided to have fun with it, say corny things, and focus on what I'm doing, it was never a regrettable experience. It was the performances that I didn't feel completely there that I have regretted.
Good luck buddy, looking forward to hearing how it went
