The Bordellofono
I certainly can't say that I invented putting a drum kit on my back, but for years it's been an idea that I've put a lot of work into perfecting. What seems like 4 or 5 instruments slapped together in a haphazard fashion is actually about 30 instruments slapped together in a haphazard fashion with a capacity of making about 300 sounds. It contains a full-length tuba and trombone, bass drum, snare, high-hat cymbal various percussions and a very special keyboard that I built myself. The keyboard fits into my hand and lets me control a large bank of digitally sampled sounds. The sounds recorded in the sampler are mostly percussive noises I've taken from cartoons and toys.
To complete the act, the instrument is loaded with LED lights, and goes with a costume equally "charged".
