Installed in a Star Waggons trailer, I remained hidden behind a wall that had a window that was painted on both sides. The audience was invited to scratch the paint on the window and to tap, bang, hit, kick or scratch the wooden wall from their side. The wall and window were mounted with pick-ups that were wired to a variety of effects modules and then amplified. I also had microphones on my side, and while singing along to the audience’s sound creations, I scratched my way through my side of the window to reach them.
