Spray paint cans -- love the sound! I could listen to this alone for a few minutes straight. Throw a pretty cool monologue about the power of graffiti art on top of that, a rogue life lesson, the frustration of an artist struggling to find a medium, then finding one (the streets) that is regulated. If you like a view from the vibrant, anarchistic, non-commercial crowd, or if you want a piece to attract that crowd, go for this.
