Consider the musical movement known as "techno". This is a style that was considered to be the next commercial success, and in a way it was. While it spawned hundreds of artists, traditional commercial success was limited. Advertisers, on the other hand, embraced it to an extent that was almost frightening. Now we hear this style in virtually every automobile commercial and in so many other media that the style itself is beginning to work it's way into our collective imagination. Techno is the embodiment of the revolution in electronic music-making machines coupled to the strongest elements of previous forms. Part of the appeal of the style is its ability to fuse the hypnotic, the trance-like, and the emotional with the sterile landscape of the obviously synthesized sound. Now that inroads have been made, a circle can be completed.
Just as techno imitated previous forms, now non-electronic sounds can imitate techno. Combined with performance art, a viable medium is at hand.
Keep in mind that the sounds techno depends on can be reproduced mechanically. The most obvious hurdle is the need for precise rhythm. The glory of the machine is its ability to keep precise time. The glory of the human performer is the performer's ability to keep almost perfect time. The sounds available mechanically will dictate the compositions. Intrinsically rhythmic sounds will be virtually effortless. Melodic and harmonic sounds must be accomplished with imagination. Natural harmonic scales can be accomplished with spinning tubing. "Sculptures" can be created that will emit music when spun through the air. Other melodic elements will depend on the talents of experienced percussionists and wind players. I propose that the troupe be artfully disguised in a manner similar to, but much more elaborate than, the "Residents". Advantage can be taken of the fact that no electricity will be required for performances.
