I happen to be a professional musician, and I also see how cool what Bobby did really was.
Now, IMO, chain saws, motorcycles, vacuum cleaners, etc, are not in the least musical because there’s no discernable tone patterns, just noise without structure.
Thanks for posting that video......made my day.
Kind of like anything by Ornette Coleman.
And I know many people who would disagree with you on those last two points. A good mechanic can tell you what's wrong with an engine just by listening to it, and I can tell you when a Mustang 5.0 is coming down the street.
If there is a rhythm to the mechanics of a system, in this case an engine or motor, why would you not think that rhythm would also translate to sound. I'm baffled by your dismissal of the obvious.
On a lighter note, the next time you see some Bikers, ask them if the sound of their hog is music to their ears. Literally.
If the sound (and vibrations) of an engine is just noise, explain why such chaos has calm, and soothing effect when your laying down in the back seat of your parents moving car.
I could go on, but what's the point....
