Outdoor on a midi keyboard

Well, sure, everything is about charity, but...
I will play a "charity" concert for the school I work for (as a part time accompanist) next January. All the money will be for the music budget of the school, and I will make sure to give a high quality classical concert. Indoors, on a good grand. The focus will be on music, anyway, and this is important. And it's a win-win situation, I get publicity and they get money for a good purpose. But music, no matter what and how and under which circumstances? No. You and your music are worth to be listened to and focused on. Just my 2 cents.
