Otherwise we wouldn't have such things as jazz or metal concepts (too name a few).

I play jazz for a living Optimus. Modes are not the corner stone of "jazz" unless you are talking about M. Davis "KIND OF BLUE" album, which was the first "modal" jazz ever written.

This happened in 1958. What about Charlie Parker? Did he miss these cornerstone of "jazz" concepts? Sure doesn't sound like it.
