this was about sound, not capability, capacity
ah, gotcha. I use similar terms for guitarists- tone & technique. Some blow ya away with tone, others technique. The HOFers to me are the one who get both at elite levels.
Similarly we're aiming for best drum sound here, not technical proficiency, right?
In that realm I'd add Buddy Miles. He wasn't a fireball but his sound was one of the most identifiable IMO.
How bout a little love for Mitch Mitchell too? Was there ever a better suited guitarist & drummer than those two together? His jazz background and ability to lead the way was perfect for JH's improvisations. See 1983, Third Stone from the Sun, etc
Don't remember anyone saying Terry Bozzio. He's HOF IMO. Has played with a ton of people from Jeff Beck to Korn. Most well known for work with Zappa. He has impeccable taste in tailoring his style to the artist or song.
