I had no idea so much went into the making of a cymbal line...all these techniques and choices for certain sounds, it's all very interesting. I also wasn't aware (haven't been around the activity in a loong time) that Diaz Clark had become such a renowned name as cymbal instructors go (props to you, Diaz).
If you mention Diaz though, the person who taught him must also be recognized, and that was a guy named Kyle "Plates" Johnson. Kyle took over the cymbal line from "Nobody" because "Nobody" was working the Cymbals before Kyle, that I know of. Kyle single handedly gave Suncoast's cymbal line a "Style" and an identity, a sense of pride, if you will, incorporating many different looks, positions and techniques that really made our cymbal line stand out as a unit within the corps. For Suncoast at least, Kyle created "Cymbal Hype."
