This thread is interesting... I went to a college that was focused on engineering, and one day I went to the library and picked up the
only music theory book they had (out of hundreds of thousands). IIRC, the copyright of that book was 1936, and the irony is that everything in that book is still applicable even today (music theory has not changed). Adding "gimmicks to sounds" doesn't not render music theory useless, yet people continue to be on an endless quest to do something "never done before."
