This piece compares the human reproductive organs to the musical instrument (specifically the electric guitar).
Aesthetically we see that the forms share similar silhouettes--long, powerful, and phallic. Both the organs and the instruments are ready to perform. The male form stands erect, while the female form is dialated and welcoming. However, the forms are again different in that the human forms have a soft fleshiness to them, enabling them to swell and contract when the time to perform arrives; whereas the guitars are permanantly hard and erect, stuck in a state of constant performance.
Conceptually we first notice the phallic nature of each form. Each piece seems to be interchangeable with one another--guitar as reproductive organ, reproductive organ as guitar. As we look deeper we see how manipulating and teasing each form with motion and friction releases the forms energy. Differentiating the speed or pressure of the motion and friction releases a very different kind of energy.
This piece is meant to exhibit the relationship between sexual and artistic performance. In showing the musical instrument as a phallic symbol, it also explains the sexual energy associated with musicians, and why people are often so sexually attracted to them.
This is also a statement about the music industry itself, and how the music and art has been replaced by sexual commercialism.
